Many of the currently popular cards will... eventually leave the meta, sooner or later. When people summon AG I usually switch the toggle button to ON; as soon a it's the battle phase I flip Reactor Dragon face down with a canadia. They would need to have fortress on field in order to make Dragon Reactor immune to traps for one turn... which isn't likely to happen. Anyway, a floodgate works better
Back in Ultimate Rising time when all we have are normal monster beatdown decks, the SR rarity card Reinforcement is such a good card, but now it has been way powercreeped by the N rarity card Paleozoic Eldonia.
RIP WoD 2017 - 2019.
Reactor Dragon is here now so you'll never be useful again.
at least it wont be seen too often, canadia is likely to lose some of its popularity thanks to AG as well. I think thats quite a good idea to change the meta and its techs instead of just limiting cards
