Spark ignition

Enchant creature.
Enchanted creature becomes a planeswalker. Its loyalty is its power plus its toughness. If said abilities cost mana, they no longer cost mana and instead cost loyalty equal to their converted mana
cost minus 1. Otherwise they add 1 loyalty.
Abilities of this planeswalker that say flip it no
longer do so. It keeps all passive abilities. It is no
longer a creature and loses all creature types.
