Combo of this deck is to try to use zabu then mystique or use sera after zabu.
If one of these combo is active then all your 4 cards are now 1 cost cards.
Goose (enemy cant use 4-6 cost cards) is so that u can ensure the lane that you put it will win so that omega red will be active (Goose + zabu + Mystique + omega + cross + rockslide)
(Goose + zabu + sera + omega + cross + rockslide)
Or if not you can try to improve to win with this deck
Update : i swapped sunspot with enchantress so that users of this deck may counter other zabu players or ongoing decks such as kazar/patriot/cerebro
