While Leatherhead, Swamp Stalker, enters with only a hexproof counter, you'll want to get some +1/+1 counters on the card straight away to avoid having to remove the hexproof counter
(A player with ten or more poison counters loses the game.) Whenever another creature you control with deathtouch dies, each opponent sacrifices a nontoken creature of their choice
