Mimic

[Rass]

I have {Eldrazi Mimic} on the field. I cast  {Phyrexian Dreadnought}. Can I sac the mimic to keep the dreadnought?

[particle]

But why sac the mimic when it doesn't have summoning sickness.

Turn 1: {eye of ugin}, {eldrazi mimic} x2
Turn 2: play {phyrexian dreadnought} let it die, swing for 24.

Trample.

Doesn't matter if your opponent is dead.
