The Honored One

Flying, first strike, shroud, vigilance, lifelink, haste

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)

Noncreature spells you play cost {r}{u} to play.

Whenever Satoru Gojo attacks, exile the top four cards of your library. Until end of turn, you may cast noncreature spells from among those cards without paying their mana costs.
Once per game: When Satoru Gojo dies, return it to the battlefield tapped.
