Wow. For every instance of damage anywhere. That's pretty potent (and also would be a total pain to implement online). It completely hoses most creature tokens from the opponent, makes most opposing Walls very vulnerable too, and generally lets you Doran or reverse-Doran any time you like.

I love the idea. I don't know if it'll turn out too fiddly to play in practice, but it definitely seems worth a try.

Because I needed to check: (Faze: Use power rather than toughness to determine lethal damage to creatures marked with faze damage.)

So; um; gibber. Things in combat deal damage equal to power, toughness, or mana. And things whether in or out of combat take damage equal to power or toughness. Your choice. Oh! And +1 and -1 counters only affect toughness now. It sure seems potent. But it is gonna paralyse combat completely, just because "My attack phase... I'm gonna need to think about what could happen. A lot... You know what? Forget this. Main2."

Unless every creature in the set is Grizzly Bears. Then it'll be fine :)

Still, it's a cube. You get to have bazonkers effects in cubes. Go for it. Though that "first ability is combat only, second ability is everything" is gonna be a nasty sticking point. Maybe find a way to fix this?

I think it might be too cheap? I'm also not sure if giving it the first and second parts is too much for one card.

I'm glad you like it, though. :)

Vitenka: I could easily add the word "combat" in the second ability.

It woulda been nicer to somehow figure out a way for the first abilty to also apply outside of combat (maybe it just does; I mean, spells don't have P/T of 0/0, they just don't have them). But this is fine.

Cheapness is stupidly hard to evaluate for a card as bonkers as this. I think it's probably ok to be really cheap; since it's only really stupid-effective once there's several creatures in play.
