honestly, your opponent is screwed against unstable gas combos unless they use fire, dark, or gravity. water cant take out unstable gases, tho the nymph could be frozen. earth can "heal" some of their health, tho if there are a lot of nymphs on the field, they dont stand much of a chance. aether has no perm control or healing, pretty vulnerable to ug spam. entropy has almost no perm control, but it can mutate, which can backfire at times and can create perm control if your lucky. life heals, nothing more can counter this card in life. light heals, same as life. time has no perm control other than a lucky hatch. air can only counter with pure power blitzes. and death, well it has nothing against ug spams (sorry).
the problem however is, almost everyone uses steal or deflag in rainbow decks. and oty is annoyingly top tier...
i have yet to face a deck with reflecting shields, so i dont know if it would be reflected, if anyone KNOWS if it does, that would be helpful.
