Bloater

Reach.
When Bloater enters the battlefield, put an
Infection counter on up to two creature's your opponent's control with Flying.
When Bloater blocks or becomes the target of an opponent ability/spell, Amass 2. If it blocks a red creature, or is targeted by a red ability/spell,
this does not trigger.
When Bloater dies, Proliferate equal to the
amount of Infection tokens you control.
