Um. So... in the absence of any imitate effects, this is 4 mana for a 2/1, which once it loses summoning sickness you can pay 2 mana and sacrifice it to kill a creature?

That's awful.

Even with imitate effects it's still normally card disadvantage.

On the flip side - a 2/1 reach deathtouch, with fight and regenerate? That's a scary card of doom!

That's after he edited it to add regeneration as well as halving the cost. (A powerful form of regeneration, too - Asceticism level.)

This is now indeed scary card of doom... but that's what mythics should be like. Unfortunately, this now also falls foul of the problem I discussed over on this card. It's putting all the pieces together to make Visara the Dreadful, which is a black card, even though all the pieces individually are green.

Red doesn't get Enhanced Awareness, even though red gets Wild Guess and Reverberate. Blue doesn't get Pull Under, even though blue gets Hydrosurge and Twisted Image. That's what the Peculiar Distortion family are all about. This card is missing the off-colour entwine cost.
