Whenever you cast or copy an instant or sorcery
spell, you create a treasure token.
When you spend treasure tokens to cast instant
or sorcery spells, put a +1/+1 counter on this creature.
Sacrifice 10 Treasure tokens: Search your library
for a card, you may cast that card without paying
its mana cost then shuffle your library.
