With wings you will destroy whole decks, just with one card. ONE!!!
I'd like to remind you that these cards still exist:
Black Hole
Rain of Fire
Pandemonium
There are probably more, but I can't think of them. In case you didn't notice, I just took apart Rainbow and RoL/Hope.
For me, because I play earth its the first step to pokemon, cant attack .
Dunno if you noticed, but this isn't Pokemon.
Really, Wings isn't OP. I just wasted two hours of my life testing it against HB and Gods. The winning percentage of a Rainbow deck with it substituted for Permafrost actually goes down, because it's makes you more vulnerable to a rush by FFQ. Against Half-Bloods, it's pretty much the same situation.
The only place where this would be stupid is in a constructed tournament where you can't switch decks, in t50 if you can take out the FFQ, or against rushes by the solid and liquid elements.
