i reckon as it is, it´s too OP, unless you change it so the effect only lasts a number of turns (like say 3 for unnuped, 4 for upped) and lower the cost by 1 quanta (leave the cost the same for both unup and up cards), that way its not permanent on the creature and is still potent
All it takes is a simple Maxwell's Demon to put this card down.
but thats just one card
Didn't I just say any CC will stop the creature?
wait one question first
so lets say there are 3 photons and i use this card to get a 3/1 photon.
if i play a photon next turn, does it become 4/1?
well if it does, please ignore me
if not, i imagine this being used as a OTK combined with fractal
