Delina, Wild Mage — Adventures in the Forgotten Realms Promos #138s

Whenever Delina attacks, choose target creature you control, then roll a d20.

1—14 | Create a tapped and attacking token that's a copy of that creature, except it's not legendary and it has "At end of combat, exile this token."

15—20 | Create one of those tokens. You may roll again.
