Cursed Samurai

Cursed 2 (This permanent enters the battlefield with
two curse counters on it.)
Whenever you cast a white spell, remove a curse counter from Cursed Samurai.
As long as Cursed Samurai has no curse counters
on it, it gets +1/+0 and has bushido 1. (Whenever
this creature blocks or becomes blocked, it gets +1/+1
until end of turn.)
