Ryougi Shiki

When Ryougi Shiki enters the battlefield, exile
up to one target nonland, nontoken permanent
you don't control with converted mana cost 4 or
less.
When Ryougi Shiki leaves the battlefield, the
exiled card's owner creates an X/X blue Illusion creature token, where X is the converted mana
cost of the exiled card.
"My turn? You really work people hard."
