sacrifice for assault

Whenever a creature you control enters, it gets +2/+0 and gains haste until end of turn.

Starting with you, each player may pay any amount of life. Repeat this process until no one pays life. Each player creates a 1/1 black Rat creature token for each 1 life they paid this way.

Whenever a creature you control enters, if that creature is 1/1, put two +1/+1 counters on it.
