Standard variation on Frost Breath, but strong. Turning into in Adverse Conditions turns your one 1/1 ground token into two flying tokens.

Remember that tapping isn't as strong in an environment with AEther canisters.

While true, I don't think that is a reason to push the power level of this effect this high. I think that this should really challenge how good tapping effects in the format, like Pacifism in a format with exploit. I agree with Alex on this one.

That said, this looks like a beating when you consider Lingering Souls.

We also have a really large amount of thopters flying around here. Consider making this a cipher card? :)

Also, since canisters are only at sorcery speed, you can just use this in combat or end of turn just as effectively.

This is just OP at the moment.

4U then?

Makes sense. 3 CMC spell + 3 CMC spell could reasonably cost 5.

Yeah, seems reasonable. It's pretty expensive now, but very good as well. It does somewhat work against itself in that you'd most like to tap the creatures before your opponent declares attackers, but most like to make the tokens after they declare attackers.

Gonna try testing this at locking down 3 creatures at as a finisher. May end up moving it back.
