Apex, Optional Being

Everything is Me —Nontoken creatures you control are artifacts, enchantments, and are every creature type in addition to their other types.

Optimization {2} — Put a loyalty counter on other nontoken creatures you control. Then, until end of turn, they lose all other types and become planeswalkers with +1: Gain 1 life and -3: Destroy target artifact or enchantment and -7: Destroy all nonland permanents you don't control. Only activate this as a sorcery and once per turn.
