(6/10/2022) Once the game begins, your two commanders are tracked separately

Sample dragon deck skeleton (The Ur-Dragon) Heres how the template comes together as a concrete 100-card list outline you can fill in: 1 Commander: The Ur-Dragon ~30 Dragons: Tiamat, Scion of the Ur-Dragon, Terror of the Peaks, Scourge of Valkas, Goldspan Dragon, Old Gnawbone, Ancient Gold Dragon, Thundermaw Hellkite, Dragonlord Atarka, Karrthus, and a deep bench of your favorites ~8 Payoffs: Dragon Tempest, Crucible of Fire, Temur Ascendancy, Heralds Horn, Morophon, Dragons Hoard, Dragonlords Servant ~11 Ramp: Sol Ring, Arcane Signet, five-color rocks, Cultivate, Farseek, Sakura-Tribe Elder ~10 Interaction: Crux of Fate plus spot removal and a second sweeper ~7 Card draw: dragon-specific and generic refuel ~37 Lands: a five-color base duals, fetches, and utility lands The fastest way to assemble a tuned list is to let our AI deck builder generate a full dragon deck around your chosen commander, then run it through the Deck Analyzer to confirm your ramp and curve are dialed in

Ill catch yall on the next one.
There exist multiple decks playing Urzas Saga, the most popular being Affinity, Amulet Titan and Hammer Time, and Force of Vigor can regularly destroy two permanents for zero mana in these matchups
I will not be adding in the Commander set since they are made for it
not as all-encompassing of an answer, but a much easier hoop to jump through (in this deck, anyway) to get there
