Hmmm... Let's see here... So creature types, art, and flavor text have all already been taken. So what is left? Aha! I know! What the card does!
This is a contest reminiscent of @sorinjace
's Creature Feature, @Ranshi922
's Picture Perfect Illustration Extravaganza, and @Tomigon
's Flavor Text Challenge. Like the other ones, the person who submits the first card that fits the criteria can request new criteria to be met. In this case, the criteria is what the card does. Some examples of this would be, "Graveyard hate" or "Cares about how many creatures you have". Try not to make them too complex.
There will be periodic deadlines, and I may even add in a challenge for the deadline. I may not though, depending on.

I will start off the chain with this simple request: A Creature that Taps to do Damage
If you have any questions on how this works, feel free to ask.
So, without further ado, Good Luck, Have Fun, and Happy Cardsmithing!
