Redcap Gutter-Dweller [Wilds of Eldraine Prerelease Promos]

Menace

When Redcap Gutter-Dweller enters the battlefield, create two 1/1 black Rat creature tokens with “This creature can't block.”

At the beginning of your upkeep, you may sacrifice another creature. If you do, put a +1/+1 counter on Redcap Gutter-Dweller and exile the top card of your library. You may play that card this turn.
