My Jalira deck works by summoning tokens and sacrificing them, then whipping huge monsters like Darksteel Colossus and Ancient Stone Idol, quirky beefcakes like Star Whale, big bodies with extra effects like Scourge of the Fleets, Phyrexian Ingester, and Sphinx of the Second Sun, and big ol fish like Stormtide Leviathan. (The deck would probably benefit from Eldrazi cards, but I find myself bored by them, so only two make an appearance)
Power Matters If theres one thing Multani has, its huge power that scales up throughout the game, so cards that care about a creatures power get even better in a Multani deck
The dungeon cards wont need to be drafted or included as part of either players deck, starting alongside each player's sideboard without taking up a sideboard slot
youll need Teysa Karlov for that
Even the lands that enter untapped, like Emeria's Call, have a cost for running, either not mana-fixing in multicolor decks or simply lacking synergies a Plains card offers when paired with cards that care about basic land types like Emeria, the Sky Ruin, Emeria Shepherd, Extraplanar Lens, etc
