Ichibei, Master of Names

Whenever a basic Plains enters the battlefield under your control, put a white counter on a target creature. (Creatures with white counters have no abilities)

Whenever a basic swamp enters the battlefield under your control, put a black counter on a target creature with a white counter on it. (Creatures with black counters become
a black Ant with base power and toughness 1/1.)

Remove these counters if Ichibei leaves the battlefield.
