its a nice adaptation of theme, but as is the cost is low- did you just pick numbers or did you do calculations to determine the cost/atk/skill balance? generally i would suggest atk value + points for having a skill (based on power and cost of skill, cost is irrelevant here), and -1 (or 2 on occasion) cost for the upgraded, so 4+1 and 5+1-1(or -2) respectively, so id suggest costs of 5 and 4 for these. have oldtrees do his own analysis if you trust him more. as is this is a rusher for
, something i recall hearing zanz did not want, but i dont know if you care about that or not.
