Seshra, Pirate Queen of Eels

Merfolk and Pirate creatures you control
can't be blocked.
Wanted- When Seshra leaves the battlefield,
each player may draw a card. Then, you create a
treasure token for each card drawn this way.
Raid - At the beginning of your end step,
if you attacked this turn, create a 3/3 blue Eel
creature token for each tapped creature
you control.
