dont get me wrong. looks like a funny pvp 1 deck.
i like your idea that the squishes you are mutating, have skills and can do a bit damage.
but if your opponent have a bit cc he will destroy your mutation table, if its a photon or a elf or a mind flyer.
agree with bluesky. seems a bit entropy heavy. maybe replace 1 elf?
my suggestions you may test:
-1 elf, -1 forest spirit, - phase spider
+ 1 quantum pillar, + 1 graviton fire eater, +1 mind flayer
...
Also, mutating the creatures with abilities DOES seem to get better results then sparks or photons, I've done mutate a thousand times. There is a definite difference.
"does seem" isnt a
"definite difference". i have seen enough mutations to fairly doubt this "theory".
