Rost's Feln Control

Set 6 Feln Control. No Blight Pass Smuggler because Kerendon Merchant lets us run banners main, making it easier to cast Rost, the Walking Glacier. Rost is effectively a better Champion of Cunning as there's no aegis conflict with Vara, Vengeance Seeker (same reason there's only one Cobalt Waystone).
Market:
Champion moved to market for when it's good.
Mug is for the combo decks.
In Cold Blood for our spot removal.
Azindel's Gift to put away games.
Feln Banner for Rost.
