Tom Bombadil

When Tom Bombadil enters the battlefield, search
your Library for a saga, play it, and put one
lore counter on it.

{2}{w}{g}: Two target creatures you control get
+2/+2, and hexproof.

{2}{w}{u}{r}{g}, Sacrifice four lore counters you control: Creatures you control gain +1/+1, Vigilance, and
four gain indestructible until end of turn.
