Megumin, Exploding Cannon

Flash, First Strike
When Megumin, Exploding Cannon
enters the battlefield, destroy target permanent.
If a permanent an opponent controls is destroyed
this way, create two 1/1 white tokens named
"Glass Cannon" that say "When this token is destroyed put a +1/+1 counter on target creature",
then exile Megumin, Exploding Cannon until
your next end phase, then return it to the battlefield tapped.
