The new format, Willpower League, is intended to be played at large-scale events like PAX Unplugged, which runs from December 1-3 in Philadelphia, Pennsylvania, but also probably can be scaled down to fit local game stores if needed
I could go on
Cards like Reassembling Skeleton, Pitiless Plunderer, and Phyrexian Reclamation keep the sacrifice engine running, letting you tutor multiple times per game
I had one time where devour came into play due to playing against a stax deck, but other than that, the small dragons really only count as blockers on their own, unless you have Scourge of Valkas or Dragon Tempest
It's going to be less efficient than other red-green decks and other counterspell decks, but if style points are more important than winning, that should be a valid option
