Control cards in Marvel Snap have functionality in various decks, but one of the most overlooked cards of this type from Pool 2 is the 5 Energy cost 3 Power Leech, whose ability disables all effects from characters in the opponents' hand On Reveal. A dastardly strategy that may lead to quick retreats from the enemy player, Leech, unfortunately, can be considered a weaker card due to its expensive cost. However, players who take the time to form a deck built around Leech's disruption may find themselves clutching out matches by limiting their foe's options late into a game.
