Dragonfire Dive — During your turn, Dion and other Knights you control have flying.
When Dion enters, create a 2/2 white Knight creature token.
, : Exile Dion, then return it to the battlefield transformed under its owner's control. Activate only as a sorcery.
(As this Saga enters and after your draw step, add a lore counter.)
I, II — Wings of Light — Put a +1/+1 counter on each other creature you control. Those creatures gain flying until end of turn.
III — Gigaflare — Destroy target permanent. Exile Bahamut, then return it to the battlefield (front face up).
Flying
Dion is a mono-white Knights/go-wide commander that builds a board of bodies, then flips into Bahamut to pump the whole team twice and grant flying for surprise alpha strikes. You deploy creatures and anthems early, transform Dion when the board is wide, ride the Wings of Light counters to lethal flying damage, and use Gigaflare as a removal reset that also resets the Saga to do it again. Mono-white lets you lean on efficient stax, taxes, and the deepest catalog of white token and anthem effects.
Repeatable two-counter team pump plus evasion makes go-wide boards close games fast.
Bahamut's Gigaflare is flexible, recurring removal for any permanent type.
Commander provides built-in token bodies and Knight synergy on cast.
Mono-white access to strong stax, taxes, and cheap mass token producers.
Mono-white card draw and ramp are historically weak.
Vulnerable to board wipes that erase your go-wide investment.
Flipping costs plus a tap, a real tempo and mana sink.
No reach or interaction in combat outside the team buff; relies on creatures resolving.
