A tiny leader cube.
Like commander but max mana value of 3 for everything. Life starts at 25, no commander damage and planeswalkers can be your leader.
I will be fine tuning the cube and eventually write up an archetype guide
Need to fine tune the themes. Mutate is out, need more madness and food in red, more tribe support beyond elves and warriors.
Potentially too many 3MV cards? I'm not sure how TL should curve out.
