Having beating A10 with everyone, Sealed+ challenges is my new favorite way to play!

If you're looking for quick pickup games with the gang or just fun solo sessions, I can't recommend Sealed enough. Having the beginnings of a tight synergy deck right out the gate instead of muddling through Strikes and Defends is a huge refresher, and it makes tackling 3 or more challenges on A10 a breeze!

There are downsides however. No strikes makes Hellraiser/Perfected Strike builds weaker for Ironclad, and no starter cards means missing key pieces like Dualcast and Unleash. Still, it's a fun accelerated game mode for a change of pace.
