Delu of Ilvano's Brush

Rider of Irisyb (As Delu attacks or blocks, you may
have him ride Irisyb. If you do, add Irisyb's power,
toughness, and abilities to Delu until end of combat.
Only ride Irisyb if it isn't in combat.)
At the beginning of each combat, create a
legendary 3/3 white and green Wolf creature
token named Irisyb with first strike, vigilance,
and hexproof. Exile that token at end of
combat.
