Xilus, The Mirage Dancer

Booming Blade: Whenever Xilus attacks, you may
pay {u}{r}. If you do, Xilus deals 2 damage to any
target and you draw a card.

Mirage Dance{2}{u}{r}: Until end of turn, Xilus
becomes a copy of another creature you control,
except it gains hexproof until end of turn.
When this creature deals direct damage, draw a card.

"With a symphony of thunder and Mirage,
I carve my legend across the realms."
