Seto Kaiba

Eminence - Whenever you cast a God or Dragon
spell, while this card is in the command zone or
on the battlefield, that card enters the battlefield
with a +1/+1 counter on it.
When Seto Kaiba enters the battlefield, add one
Dragon from your graveyard to your hand.

if both have Ace Monster, and one is a Duelist.)
