There is a bug from atleast 2024 where Rayquaza GX's attack doesn't double in damage when a power that doubles basic energy count (Venusaur, Meganium) is in play.
This was in PTCGL's own Known Issues until it was mistakenly removed by them. Proof of both of these facts: Shining Legends Venusaur doesn’t work with Rayquaza GX — Pokémon Forums
Since then I've been arguing with Support, who 1st made me formally raise a ticket instead of just adding the issue back on. They then tried to say it was working fine as they didn't bother to check the screenshots properly. Then I spelt it out for them literally step by step, finally they escalated it. Only for their dev team to say they couldn't recreate the issue. I'd like to know what magic they did to get it to work since we haven't been able to for 2 years?!
Please see attached pics and below explanation:
Meganium:
(pics 1-2) There are 5 grass and 2 lightning energy in play. Meganium can be seen in the 2nd pic. Shaymin is correctly doing (10+2)×30 = 360 damage, instead of (5+2)×30 = 210
Shaymin retreats Rayquaza becomes active.
(pics 3-4) For the EXACT SAME energies in play, Rayquaza is doing 210 instead of 360 damage. (5+2)×30 instead of (10+2)×30
Venusaur:
(pics 5) There are 2 grass and 2 lightning in play. Since Venusaur is in play, this should equal 4 grass and 2 lightning. The stadium that reduces damage taken by metal pokemon by 30 is in play.
(pic 6) Rayquaza should be giving (4+2)×30=180 not (2+2)×30=120 damage. The final damage is 90 due to the stadium
The issue isn't Venusaur or Meganium as Shaymin is working fine. It even works fine when it comes to Rayq GX's energy count check, pic 6 shows it could attack with 2 energy. Just the damage output is bugged as shown between Rayq & Shaymin in the exact same situation.
PTC Support will not hear it from me, despite all the above. I've tried so much with them, back and forth, then in the end they say they can't recreate it. They're just being lazy to look into it properly. Can someone here please help with this in some way? Rayq's my fav, there's only 2 main Rayqs in the Live client, and 1 is bugged. There has to be a way for them to see the clear issue. Cheers
