Paradox making a... control deck?
This is a slightly more unit-based control deck, though that's sort of what Feln has always been. x4 Annihilate because Time is everywhere and it kills everything. Kenna is a sweet late-game threat that can draw in a ton of value. Observer helps you filter, get card advantage with Jotun Hurlers, and activate tribute for Kenna. Dark Return helps you get multiple Merchant uses and synergizes with all the discard and self-mill.
Market is where this deck gains everything. Burglarize gives you an answer to Relics. Putting Champion of Cunning in the Market is awesome because it's such a slow card to have in your hand in many matchups. Azindel's Gift is also great, but never a card you want mainboard. ICB is just an extra kill spell. Don't know what to do with the last spot, so for right now it's Steward.
edit: Didn't like Torgov. Switched to Jotun Hurler, who helps with aggro, breaking aegises, activating Tribute, and putting cards into the Market. Haven't looked back.
this makes LSV proud
