If the first iteration destroys it, does the second iteration still happen? Specifically, if an otyugh Devours this, will it gain +2 | +2 for having done so?
Also, this might just be OP in a deck like Little Miss Fire. It doubles the effect of buffs just like Deja Vu does, but then it also doubles the effect of PU, making it 1.5x faster than Little Miss Fire already is. That's extraordinarily dangerous.
