Sylvie & Phaerya, Oathsworn

At the beginning of your end step, each player
exiles the top card of their library. Until your
next end step, each player may play the card
they exiled this way.
Whenever a player plays a land from exile
or casts a spell from exile, you put a +1/+1
counter on target creature and create a Food
token.

A friendship to share with the whole world.
