The idea of the deck is to give blacksky or yetipult deadly by drawing them will the inspire unit is on board or merchant for the backsky in the market while the inspire unit is on board and giving it deadly. Then when you summon the yeti or the blacksky it kills 3 things or everything with the damage pings
Vara unit and spell is in there to prevent aegis protection and is a good threat in its own right
You can also use things like dragon breath etc on your deadly units to remove single threats
