Satoru Gojo

Indestructible, haste

Hollow Purple — If you have cast a red spell and
a blue spell this turn, you may pay {r}{u} and
sacrifice a Cursed Spirit creature you control. If you
do, deal damage to target opponent equal to that
creature's power.

When Satoru Gojo leaves the battlefield, you get an
emblem with "All Cursed Spirit creatures get +1/+1"
