Aregorious, the Giver

Eminence — As long as Aregorious, the Giver is in
the command zone or on the battlefield, Fish spells
you cast have, "Gift a tapped Fish". (As you cast
a spell this way, you may promise an opponent a gift.
If you do, they create a tapped 1/1 blue Fish creature
token before the other effects of a spell cast this way.)

Whenever you give a Gift, draw a card for each
player who controls a Fish, then tap up to one
target creature an opponent controls.
