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
The deck does play other extra mana effects to help cast your dragons because they're usually expensive in cost
Warden of the GroveWarden of the Grove is the clear best card among all of the enduring ones: it's cheap and easy to cast and it snowballs out of control very quickly
FromTheShire: Oh we're one million percent seeing this for the bit
while you dont see much of it in Commander (at least, I dont), its a stunning Cube card that offers red decks a variety of powerful effects
Kuzco is great at forcing bad choices on your opponent
