We are starting to see cards like Sneaky Git that say something like this:
"Action: When this unit attacks, reveal the top card of your deck. If the revealed card is odd, deal 2 damage to target capital. Otherwise, deal 2 damage to your capital. Then, shuffle your deck."
In a goblin deck (let's just call it a "rush deck") some people try to get away with loading up their cheap units with lots of free attachments. Pretend I try to activate Sneaky Git's ability and I flip over Tribal Tattoos or any other 0 cost card. I could see how 0 could be considered "Not odd, therefore even" by me since I want the action to work, and considered "Not even, therefore not counting in this situation as activating the ability" by my opponent. I was commenting on someone else's deck and they adamantly claimed 0 is odd "according to maths." That's interesting, because according to Wikipedia (otherwise known as the INFALLIBLE SOURCE OF INFORMATION, SHUT UP IT'S TRUE) 0 is even. http://en.wikipedia.org/wiki/Parity_of_zero
So what do you guys think? I figure it could be played as even or it could be played as "neither even nor odd, get out of here Einstein." I will call it even if my opponent ever flips it though.
