Crucias, Titan of the Waves

At the beginning of your end step, you may
discard a card. If you do, create a Treasure token
and choose ambitious or expedient. If you chose ambitious, reveal cards from the top of your
library until you reveal a card with greater mana
value than the discarded card. If you chose expedient, reveal cards from the top of your
library until you reveal a card with lesser mana
value than the discarded card. Put that card into
your hand and the rest on the bottom of your
library in a random order.
