Ah. A great idea and I had stored away basically something exactly like this, mechanic and name! Though your version has stats and cost which I'm liking more than my version. Hah.
Anyway, good to see it out here. Some recommendations though:
While Mitosis (the spell) does produce a cost of the creature's cost, a reproductive skill such as Mitosis, especially if not given through the spell should try to cost
, at least for thematic purposes. An increase of the standard version's HP to 2 would produce more synergy with Dry Spell, but also create more of an elemental distinction from
Fire, an element of highly fragile creatures. Lastly, in order to really separate this from a simple Aflatoxin on Spark, perhaps both the standard and upgraded versions could produce
per turn, being Water's token type of creature? I think that would really give it use and create some possible pillarless decks.
Just my 2
. Continue the great work!
