Spoils of the Gourd

At the beginning of your end step, sacrifice a token or a Plant. If you do, create a Food token.
Whenever you sacrifice a permanent for the first time each turn, you may choose one —
• Add {r}.
• Pay {w} and create a 1/1 white spirit creature token with flying.
• Pay {u} and put the top card of your library in your graveyard.
