Ink!Sans

Ink!Sans enters the battlefield with two SOUL counters on it.
Remove a SOUL counter from Ink!Sans: change
all instances of color on target spell to a
single color. (Color identity, mana costs to activate abilities, and the words white, blue, green, red, and
black all become a single color. This doesn't affect
casting cost. If the spell is a permanent, these
effects last until it leaves the battlefield.)
