Is this a serious post?... This card would be so OP...
This is a serious post.
Is it OP though? First off, can it be OP when it can't possibly make your deck more effective in battle?
It's only real use is in the arena (and trolling) and it's better to just win the game and get on to another one than to wait to draw more/any of these. It makes the deck worse and probably would take more time to try and battle with drawing lots of these (if you do that it doesn't matter too much if you win or lose) than just beating 1 hp decks and moving on to the next one. So 6 of these in a 1 hp deck farmer is the only good use I can think of for them.
