Omnimon

When Omnimon enters the battlefield, choose one or both:

Garuru Cannon — Exile target tapped creature.

Grey Sword — Omnimon deals 6 damage to each creature that attacked this turn.

If you control both a creature named WarGreymon and a creature named MetalGarurumon, you may sacrifice them
as an additional cost to cast Omnimon. If you do, Omnimon gains double strike and hexproof.
