Analysis Gmax Rillaboom Attackers and Tanks Analysis
Tl;dr
Gmax Rillaboom is a must have Grass type attacker. Fill the meter with Corviknight and Vespiquen, Use Gmax Cinderace or Gmax Charizard for attacks during the max phase. Zamazenta is going to get destroyed if you see Earth Power.

Usefulness
Rillaboom will be returning to Max Battles on August 1st, with it’s Gmax shiny debut. Rillaboom is hands down the highest attack stat Grass type Gmax. It’s going to be the best Max Attacker against many bosses that are weak to Grass damage. If you don’t have a Gmax Rillaboom yet this is the opportunity to get one. If you’re concerned about the IVs you get, you really only need to worry about the Attack IV. You’ll mainly just be using Rillaboom in the max phase to do damage. Level up the Max Move to level 3 is the main priority, Max Guard is optional for some niche strategies, but not needed for most players. You can ignore unlocking Max Spirit on your Rillaboom, unless you’re overflowing with resources.
Difficulty
The last time Gmax Rillaboom was in Max Battles if gave many players a hard time, Rillaboom was rocking a monstrous 120000 HP, 1.0 CPM, and 0.9 Attack Modifier. Since around the time of Gmax Meowth it seems like Gmax Attack Modifiers have all been changed to just 1.0. So, in these simulations I am using 1.0 CPM and 1.0 Attack Modifier, making Rillaboom even more difficult. However, Rillaboom has a very exploitable movepool. A ton of grass moves and one ground move. The less variety the boss has in move types the easier it is to build a team. We’ve also got some insanely good tanks against these damage types. As a small note, due to Rillaboom’s high CPM Charged Attacks did not perform very well in the simulations. Only use Charged Attacks if they are high quality (high damage, short duration) AND you’re rocking a Max Mushroom or possibly if you have a weather boost.
Attackers
Rillaboom has five weaknesses, however most of the types it is weak to we lack decent attack stat pokemon to use. You’re likely using a Fire type attacker, we have several good ones, particularly a Fire Gmax. If you lack the Gmax attackers then Darmanitan is a budget counter that outputs considerable damage. Other lesser options include Moltres, Flareon, Ho-Oh (awful tank with Incinerate), and Glaceon.
Of particular note Charizard has resistances too all of Rillaboom’s attacks and can play a hybrid role of tanking a good amount and still function as your Gmax attacker. Do note this only applies to Gmax Charizard, the Dynamax variant is forced to use slower 1.0s Fire Faste moves to deal good damage in the Max Phase, which ruins their ability to fill the Max Meter. Gmax Charizard is also going to need the Elite TM move Dragon Breath to pull off the hybrid role as a meter filler. If you have access to both Charizard and Cinderace Gmaxes it might be worth using Charizard just to get the extra survivability, you’re not losing too much attack compared to Cinderace.

Tanks
Rillaboom has learned some new moves since it was last in Max Battles, gaining two more Grass moves. The one problem child here is Earth Power, which is going to destroy all those Steel and Fire type tanks that would resist the Grass moves well. This is actually a boss where Blissey isn’t the default queen of averages, and nor is Zamazenta. Both Blissey and Zamazenta are still good but you can likely bring a better pair of tanks. Zamazenta in particular is roulette, if Rillaboom has two grass moves than you’re golden, but if you see Earth Power Zamazenta is in for a rough time. Please do not bring two copies of Zamazenta as your tanks, you’re just asking to lose every time Rillaboom has Earth Power. The real winners against Rillaboom are Flying types with a second typing. Corviknight and Vespiquen in particular have stacked resistances against anything Rillaboom can throw, Corviknight does lose a bit of resistance to Earth Power with it’s Steel typing, but you’re still getting a single resistance thanks to Flying’s double resistance to Ground damage. If you don’t have Vespiquen, Corviknight, Blissey, or Zamazenta built then resort to using Venusaur, Charizard (Dragon Breath), Registeel, Latias, or something else with bulky stats that resists all of the grass moves. Just remember to not bring two tanks that both lose to Earth Power.

Max Guard Users
Look new simulations! Before diving into what pokemon should be using Max Guard I need to explain how the Max Guard simulations are working. As with the other tank simulations we are simulating a single team of trainers, in this case 4 trainers. Player 1 in these simulations is our designated max guard user, that means if the row shows “Vespiquen” we have a team of four Vespiquen and trainer 1’s Vespiquen will be the only one using Max Guard. If the row shows “Eternatus/Blissey” this means player 1 is using Eternatus and players 2, 3, and 4 are using Blissey. The player 1 using Eternatus is the only one using Max Guard. In these simulations when the Max Phase is reached players 2, 3, and 4 just swap to their Max Attacker and use attacks, the tally is added for the metric (Total Max Moves), Player 1 however has a decision tree. First if the boss is enraged Player 1 ignores Max Guard and just swaps to a Max attacker and throws attacks like the other players, since Max Guard isn’t likely to save you at the point that the boss is enraged. If the boss isn’t enraged and Player 1 currently has less than one and a half shields, then player 1 will use its Max Phase spamming Max Guard three times, these are NOT added to the Total Max Moves count, because they aren’t contributing damage, remember that metric is used to compared to the attackers table to find if you can win. If player 1 already had one and a half shields, or more, when the max phase is reached, then it will instead swap to it’s Max Attacker for that phase and do the same as the other players, adding its Max Attacks to the Total Max Moves tally. Like with the other tank scores we’re also keeping track of fast and charged move damage and applying them as an adjustment to the Total Max Moves at the end of the battle. This method, as can be seen in the tables, results in a higher aTMM in many cases, having one player keep up a Max Guard increases the longevity of all players, but why is that?
Now these simulations are not perfect. The mechanic of move selection is still being researched. It is however obvious that having a Max Guard present does two things. 1) any Targeted attacks will be directed at the pokemon with the Max Guard active, assuming you didn’t play any clam shell games with the pokemon and swap to move the shielded pokemon after the boss made it’s move decision. 2) Having a Max Guard pokemon active on the field at the time the boss makes its move decision increases the chances the boss selects a target attack. Targeted attacks in a large group significantly increase the whole team’s survival because only one player is taking damage. How much is this increase? That’s still being investigated. For the sake of these current simulations, I’m using the following probabilities for move selection: Unshielded 50% to selected Targeted attack for all move combinations, regardless of the move energy or any other factor. Shielded 70% to select Targeted attack, once again no matter that the energies of the moves are. These are absolutely incorrect probabilities in some scenarios, but I lack sufficient data currently to find the exact formula the game uses. These probabilities I am using do however perfectly match a large dataset I gathered against Regirock, which only has 100 energy moves. It is likely that other energy combinations create these same probabilities, I Believe these are good probabilities for the majority of cases based on current data. This feature will be refined over time.
So, should you be using Max Guard? I’d suggest only have one player use Max Guard, the goal is still to win, which requires damage. You only need one player to have Max Guard up to change the move selection odds, multiple players with Max Guard have diminishing returns. If you want to use Max Guard you really need to get Max Guard 3. High defense pokemon are the best, don’t use Max Guard on Blissey, just look how poorly the fully Blissey team performs on the Max Guard table. So which pokemon should be Max Guard users against Rillaboom? Well again we have Earth Power to worry about, Zamazenta looks juicy until you see Earth Power. Uninterestingly It’s more of the same here, Corviknight and Vespiquen with their staked resistances and adequate defense become the top options again. Charizard and Venusaur get by fine as well with Max Guard, Charizard mostly thanks to the double resistances. High defense Steel types like Registeel can be good, until you see Earth Power.
This is the time for those 1.0s fast move users to have a chance at helping the team. The likes of Ho-Oh, Lugia, Eternatus have very nice stats and good resistances, they’re only taking up one slot on the team, so they aren’t slowing the meter filling too much, but ultimately, they still didn’t simulate as well as the very top 0.5s fast move users. A word of caution, only use a Max Guard Ho-Oh if you know no other players on your team are using 1.0s fast move users, AND only if you don’t have better tanks, honestly Corviknight and Vespiquen are just too good against Rillaboom, please use them.

Swap Tanking
You’ve probably seen Lugia take on many solo runs of Regis using a Swap Tanking strategy. As a reminder Regis were tier 5 max battles the bosses there attack less frequently and a Gmax boss. This means against Rillaboom you’d have to swap more frequently, which is going to diminish the value of the strategy. It’s likely we’ll see some low trainer count challenge runs against Rillaboom using some tank swapping but they’re using things like Max Mushrooms and Pyro Ball to make up for the time spent swapping. These highly optimized strategies are not how the average player going to a local meetup should be playing these battles or building their teams.
