WinterFenix 15
This deck is all about damage and large amounts of it. You want to mulligan to a hand that has at least a Sith Holocron or It Binds All Things in it. If you have multiple copies, even better.
Darth Vader - Dark Apprentice is normally the first target from the opponent due to his great special ability and 3r stick side. This allows for building up upgrades on Kylo Ren - Vader's Disciple and using force illusion on Vader.
The deck can be hungry for resources but do not be afraid to claim the battlefield early if you have a Vader die out or need that last 3 damage. The deck could probably use more die removal but with No Mercy, cards that are colorless like Doubt don't really fit in.
