Summon: Fenrir

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.) I — Crescent Fang — Search your library for a basic land card, put it onto the battlefield tapped, then shuffle. II — Heavenward Howl — When you next cast a creature spell this turn, that creature enters with an additional +1/+1 counter on it. III — Ecliptic Growl — Draw a card if you control the creature with the greatest power or tied for the greatest power.
