I think the one thing I would've liked to see more of in the list are summon cards: if you look at our commander options, Tidus, Yuna's Guardian and Yuna, Grand Summoner, both clearly work exceptionally well with the new summon creatures like Summon: Valefor as Tidus can remove lore counters to keep them around longer and Yuna can pump up creatures when the summons die, and that's a unique new game design space that would differentiate the deck from more generic +1/+1 Counter lists out there
For example, if you cast a sorcery spell that deals 4 damage divided as you choose among any number of targets, you could have it deal 3 damage to one creature and 1 damage to a battle
Expansion may only be able to copy smaller spells, but you can use the Explosion side to pull you miles ahead on the spot
There is no moment during the turn Drownyard Behemoth enters the battlefield in which it doesnt have hexproof
Once a chapter ability has triggered, the ability on the stack won't be affected if the Saga gains or loses counters, or if it leaves the battlefield
Once they have all of the pricing data (which again is based on current sales through their site), they are able to put together tracking charts and list out market prices, median prices and target buylist prices for anyone to view for free
