Winter Crown Scream

In theory The Winter Crown is quite strong if you're ahead: it draws you cards when you're able to attack the face with units, and the stun lets you lock down two blockers for 3 power a turn. This deck tries to leverage The Winter Crown in an aggressive leaning Feln deck, where Haunting Scream works nicely as both burn and a way to trigger Crown when unable to attack on board. Argenport Instigator and Black-Sky Harbinger also allow for triggering Crown without attacking.

Desecrate was also a significant card for this sort of Feln strategy, as it provides another efficient removal spell and allows cutting Permafrost in order to play Vara, Vengeance-Seeker, who otherwise has excellent synergy in the deck.
