Less powerful than Ancient Animus because multicolored is much more prevalent than legendary

Kinda depends on the set. Normally this'd be +1/+1 counter if (set theme). But sure, it still performs its main function like this.

@Vitenka you're not wrong. This set also has level counters, so that's another reason not to use +1/+1s I suppose.

It could give a level up if applicable, instead of the +1?

Well as I intended level up to be in WBR primarily, I don't have any green levelers right now. But I'll play around with it.

Ok, so this is now completely different from whatever was being discussed; I guess?

Will this trigger the life-gain if the creature doing the fight dies? That seems situational, but could do with clarification either way.

­Time to Feed would be the precedent for the wording..

Is the intent to gain 4 life even if both creatures die?

@Tahazzar thanks - that seems like a good template precedent.
