Theodosia (Delina, Wild Mage)

Whenever Delina, Wild Mage 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 "Exile this creature at the
end of combat."
15-20 | Create one of those tokens. Roll again.
"Kano, could you pass me the mustard seed
and goat's eye?"
—Theodosia Darlson
