Nerf Unstable Shapeshifter

[serprex]

I figured Shiftergon style OTK would be gross

Possible change: limit shifter to changing once per ply. This'll stop shiftertal because only the last played shifter will become a dragon (the others will've spent their transformation on shifting into shifters)

Such a change would disrupt pixiegon too, where shifter casting trick after shifting into a pixie wouldn't shift itself into a dragon too

Other possibility: a chance to become a mutant when shifting

it's not that OP, I tried it and it needs a bunch of luck in the last 3 cards
