I think it'd be neat if everyone were to create a card based on their screen name. So I'm starting it off (I doubt anyone will follow suit :-p ).
Name: Demagog
Type: Creature
Element: No idea... doesn't really fit into any of the elements
Cost: 5
Attack/health: 1/4
Ability: costs 1 quantum, name could be "speech" or "preach" or "propaganda" or "convert" I couldn't care less... anyway what it does is this: Target creature takes one damage. If target creature is killed by this effect, it appears on your side.
When it appears on your side of the field, it's at its regular attack/health.
The upgraded version, "Demagogue," is pretty much the same, just has one extra attack.
It's a decent card in my opinion, basically a weak version of TU, but it can kill (slowly). If you get two or three of these on your side, you can slowly convert all target-able creatures your opponent controls. It's easily killed though since it has only four health.
Suggestions are welcome, especially if they regard which element this should fall under and what the ability name should be, and if you want to suggest different names for the creatures, that's fine too :-p
