Ramaraw, Ninja Opportunist

Legacy - When this creature is destroyed, it becomes
an enchantment that is no longer a creature.
At the beginning of combat on your turn, create
a 0/1 spirit decoy creature token with haste that
must attack this turn if able.
The Ninjitsu costs of ninja creatures you control
cost {u}{b} less to cast. (This can only decrease
the colored mana needed to activate the ability.)
