Ensa's Vagabond

Shroud (This can't be the target of spells or abilities.)
Whenever a creature with toughness 2 or less is
tapped or exerted, put a Lore counter on this,
and you may pay {2} to untap that creature.
Remove a lore counter from this, discard a
noncreature: Look at the top two cards of your
library. Put all creatures into your hand and exile
the rest.
Remove three lore counters from Ensa's
Vagabond: empty the stack.
