Perseus, Savior of Olympus

When a permanent you control gains a quest
or lore counter, you gain an experience counter.
When Perseus deals battle damage to a player,
search your library for an enchantment card,
then, place one enchantment onto the battlefield
with converted mana cost less than or equal to
the number of experience counters you have.
Perseus gains effects based off of the number of
experience counters you have;
• 1+: Islandwalk
• 5+: Indestructible
