I was just wondering if I could get some general info on the Quentyn martell character agenda deck? Is summer the stronger deck or does it just make the deck too slow? Is Quentyn versatile enough with control and draw or does summer add more to make the deck stronger? I have both builds but just don't know where to go any help would be greatly appreciated.

To be honest, you're probably much better off asking this on agotcards or cardgamedb (the latter is owned by FFG as well), where traffic is much higher than this forum.

That said, both decks have their place. It depends which summer effects you're keying off, and what you're expecting in the meta. The more heavily you want to run event cancels (Shadows in the South), Oberyn's Shield Bearer, or when your gold curve trends high with Bannermen or Ghaston Grey, you might favour summer. If you want something that moves a little faster or works a little more aggressively, summer's probably not ideal.
