Ben 10

Eminence—As long as Ben 10 is in the command
zone or on the battlefield, whenever a nontoken
Alien you control dies, draw a card.
Whenever Ben 10 enters the battlefield or attacks,
reveal the top card of your library. If its an Alien,
you may play it without paying its mana cost. It
gains an Echo cost equal to its mana cost.
Discard an Alien creature card: Ben 10 becomes
a copy of that creature until end of turn.
