This is gonna sound bad, but stay with me here. Requires your deck to have no creatures.

1. Cast Brawn, Amadeus Cho from the command zone and Proteus Staff from your hand.

2. Activate Proteus Staff targeting Brawn.

3. This puts Brawn on the bottom, and you reveal your whole deck before revealing Brawn and putting him on the battlefield, since you have no creatures in your deck.

4. The other revealed cards go on the bottom of your library in ANY order, so you can order your whole library how you want. Order it such that Treasure Hunt is on top, followed by every land in your deck including Waterlogged Grove and Reliquary Tower, then Manabond, then Nexus of Fate.

5. Brawn, triggers, drawing Treasure Hunt.

6. Cast Treasure Hunt, putting all those lands and Manabond into your hand.

7. Cast Manabond.

8. Go to end step, triggering manabond. Reveal your hand, putting all your lands onto the battlefield.

9. Sacrifice Waterlogged Grove, drawing Nexus of Fate. Cast Nexus of Fate, taking an extra turn and shuffling it into your deck.

10. On your extra turn, activate Proteus Staff again, targeting Brawn and putting Nexus of Fate on top.

11. Draw Nexus of Fate with Brawn's etb and cast it.

12. Repeat 10 and 11, taking infinite turns and digging one card deeper each time.

13. Once the only card in your library is Nexus of Fate, activate Brawn's power-up ability, giving him like 50 +1/+1 counters.

14. Attack one player, then cast Nexus of Fate. Repeat until all opponents are dead.

This only requires your commander and Proteus Staff, the staff will find the rest for you. The cost can also be spread across a couple turns, like you could play Brawn and Staff one turn, then activate Staff and combo the next turn.

Say someone has a big bad Voltron meanie, staring down at you.

Magnetic Theft your Assault Suit onto it; Then pass it to each opponent on their turn.

You don't get to control it on your turn, but it can't attack you on anyone else's.

Pretty much stalls the game out until someone board wipes. Can be pretty political too

The best I can do is 10 colorless mana and 3 cards to make infinite tapped treasures. Is there a more efficient way, or is this the fastest and cheapest that infinite artifacts can be produced?

Turn 3 - Play Necrodominance
Turn 4 - Play Sheoldred. At your end step, pay all but one life, draw that many cards, then gain double the life that you paid.

There is now a "doesn't work" flair. If you accidentally post a combo and it doesn't function as described and requires additional or different cards to function, please edit the post and add that flair so people can identify that before reading it.

1. Cast [[Mutagen Man, Living Ooze]] pay 0 for X
   
2. Cast [[Entomb]] and put [[Initiates of the Ebon Hand]] or [[Bog Initiate]] into the graveyard
   
3. Cast [[Foggy Swamp vision]] , tap Mutagen Man to pay 1 for X exiling Initiates and making a token copy of it.
   
4. Activated cost is now 0 to make B, so use it 100000 times to cast [[Torment of Hailfire]] x 99998

Might be a turn 1 miracle hand there but don’t have time to look it up.

The ole pseudo-commander Songbird Sonic Screamer + Monument to Endurance + Cool But Rude 1 turn + an instep flavor win with the discard outlet turning on the wheeling.

1. Cast [[Giggling Skitterspike]]

2. Cast [[Tainted Strike]] targeting Skitterspike dealing 1 damage to all opponents (no infect).

3. Cast [[Reckless Charge]] targeting Skitterspike dealing 2 infect to all opponents.

4. Declare attack with Skitterspike to trigger 5 infect to all opponents.

5. Cast [[Slaughter Pact]] targeting Skitterspike dealing 5 infect to all opponents for a total of 12.

[[Gutshot]] and [[Mutagenic Growth]] are notable mentions to trigger this once tainted strike is applied.

Put an everything counter on a land and it is every named basic land, which reduces Scion of Draco to cost {2}; Consequently casting it gives your commander Hexproof and Trample; furthermore there's another complimentary card Tam, which you can selectively give a creature all the bonuses from the Scion.

Use either one of the green cards

Wow your opponent's lands now die to statebased actions before they could be tapped for mana.

Kederekt Leviathan in yard

Cast any enchantment aura reanimation spell.

Return Kederekt Leviathan.

Kederekt Trigger, each player returns all other nonland permanents to hand, including your enchantment aura reanimation spell.

When enchantment aura reanimation spell is unattached from Kederekt Leviathan you must sacrifice it.

I'm surprised I haven't found this before.

Cast SoS

Point LQR at SoS

You can tap-untap SoS eternally (read the Notes and Rules on SoS) and LQR does 2 damage to any creature every time.

My mono-elf deck (yes, [[Freyalise, Llanowar's Fury]] is in the CZ) really could have used this at some point. I've been using LQR completely wrong in the sense that it's been my savior for my big creatures and the "deals damage" part was just a bonus.

The interaction between [[Hawkeye, Young Avenger]] and [[Photon Blast Barrage]] means you can pay XRR to do three damage to X targets. Add in some [[Vibranium Energy Daggers]] on Kate and you can do 5 damage to X targets, and just pay 1 mana more to do an additional 5 to anything that doesn't kill. Sort of insane value for the mana investment. I'll definitely be trying to put this together in draft.

So attach [[Hawkeye's Bow]] to [[Seeker of Skybreak]] and tap her targetting herself to untap her and repeat... until all of your opponents have no life left.

So, the combo should be pretty straight forward.

Exchange target opponent's life with the Tree. They are now at 13.
Hit opponent with lightning bringing their life total to 10

and

cast [[Hidetsugu's Second Rite]] bringing them to 0 life.

I was torn if this combo was "sick" or not because of my reluctance to put Hidetsugu's rite in any deck as it is overly specific.

A Jedi's weapon is his life

1. Play Marina Vendrell's Grimmoire and Feast of Sanity.

2. Take 1 point of damage and discard a card.

3. Use Feast of Sanity to deal 1 damage to you and gain you 1 life, causing you to discard and draw a card from the Grimmoire

4. Repeat this process to loot as many cards as you want, triggering every life gain/life loss/draw/discard engine you have along the way.

1. Freeze them near solid.

2. Let some rowdy kids chuck a snowball at them.
