Pestbrood Sloth

The value is on the back end, not the body. A 4/4 with reach for four mana is a fine defensive stat-line, the kind of creature that trades up and swats fliers without complaint, but the design is really about what happens when it stops blocking. On death it leaves behind two Pest tokens carrying the small lifegain rider Golgari sacrifice builds have run for years: each Pest that attacks buys back a point of life, so the creature keeps paying out after it is gone. That death trigger is what turns a stat-line into a build-around. It rewards a shell that wants bodies to sacrifice, tokens to sacrifice again, and attackers to convert into incremental life, and it does so without asking you to protect the Sloth at all: you would just as soon it dies. The Pest token itself, a 1/1 whose attack refunds a point of life, is a recurring black-green template, and stapling two of them to a durable body is a clean way to make a blocker that also feeds an aristocrats engine. The reach keeps the front half honest against fliers while it waits to be cashed in; the tokens are why the card belongs in a list that reads its own creatures as fuel rather than as assets worth defending.
