I honestly feel like "Counterattack" MIGHT be conditional enough to be fair. I mean, when you think about it, it would only be useful under very specific conditions. Honestly, the best situation for that card to be used is if your opponent controls "Red Dragon Archfiend" and you control "Superheavy Samurai Big Benkei". This means that rather than your opponent taking 500 damage and you losing your monster, it's your opponent losing their monster. Srsly, best case scenario I can think of. It's like Yusei's "Counterattack Beacon". Only time that thing worked was conditional as crap.
I don't know. I'll let UE judge and we'll see
And although the art you found is cool, Eklipse, I'm hoping you recognize that "Ultimate Warrior" is too much of an uber to be accepted. Only reason I let the "Demon Lords" in is because it takes four turns to get the big one out, and before he comes, it's not too hard to destroy the others. (Especially if you're Charak with all his attack negation power)
However, congratulations on creating your first card. Now, let's talk business. If you need help making cards, I'll be more than happy to offer my services. Simply PM me, and we'll get to work.
EDIT: Actually, when Scar made "Counterattack, I realize now that he just made the absolute best way to beat "Demon Lord LV4" before he can pull out LV6+.
