Muse's Amusement

Whenever a Warrior creature you control enters
the battlefield, put a bonds counter on it.
Creatures you control with bonds counters on
them cannot attack. Whenever a Warrior creature
enters the battlefield under your control,
add {w}, {u}, or {r} to your mana pool.
Pay {r/w}{u/r}{w/u}: Remove all bonds counters
from all Warrior creatures that you control.
