Euru, Acorn Scrounger

When Euru enters, you may forage. When you do, conjure a card named Chitterspitter onto the battlefield. (To forage, exile three cards from your graveyard or sacrifice a Food.)

Whenever one or more Squirrels you control deal combat damage to a player, you may sacrifice a token. If you do, put an acorn counter on each permanent you control named Chitterspitter.
