White weenie decks don't really have a use for all that extra mana should they fail to Armageddon, so trading two mana for one more point of damage each turn stands as a pretty fair bargain
(6/16/2023) If the creature you choose as your Ring-bearer was already your Ring-bearer, that still counts as choosing that creature as your Ring-bearer for the purpose of abilities that trigger "whenever you choose a creature as your Ring-bearer" or abilities that care about which creature was chosen as your Ring-bearer
So if you have Summon: Bahamut in play with one lore counter, and you proliferate it twice to land on Chapter III (draw two cards), you'll also get to trigger Chapter II (destroy a creature)
Both sets share an almost identical card pool, and the languages look kind of similar
You need a specific objective or a certain board state before you even consider investing resources to crack open the battle (apart from discarding a card, paying three mana, and tapping this thing)
Now seems like a good time to put our speculating hats on to try to guess who will be the best of the ONE commanders
