From the Outsiders release notes

A card has Gustwave in its name if “Gustwave” is one of the whole words of one or more of the names of the card. If a card has no name, it does not have “Gustwave” in its name.
Banishing a card from your graveyard is optional. If you do, searching your deck is mandatory.
While searching, you may fail to find a card with the same name as the card that you banished. Even if you fail to find, you must shuffle your deck.
If you do not play the banished card this combat chain, it remains banished.
Decreasing the cost to play a card does not decrease the actual cost of the card for the purposes of effects that reference cost.
