Faern, Keeper of the Relics

Defender
At the beginning of each player's end step, that
player creates a Treasure token. If it's your turn,
you may abound.
Whenever a player sacrifices a Treasure, Faern
deals damage equal to its power to that player. If
it isn't your turn, Faern loses defender and gains
flying. If it already has flying, put a +1/+1
counter on it instead.
