Gandalf, Party Guest leads a Jeskai legendary Wizard spellslinger deck. It fills the board with legendary Wizards so Gandalf's beginning-of-combat trigger can cast bigger instants and sorceries from hand for free, ideally the expensive bombs like extra turns, cascade spells, free-cast spells and ultimatums. Around that engine, the Wizards and enchantments turn every instant and sorcery into cards, tokens, damage, copies and cost reduction, while trigger doublers multiply each payoff. How it wins: The deck wins by chaining spells into burn and token or Wizard combat swarms, with extra turns and extra combats closing out games, and it can also win outright with Approach of the Second Sun copied by Narset's Reversal. Key roles: - Legendary Wizard density: Gandalf, Party Guest's free-cast threshold grows by two for each legendary Wizard, so the many cheap legendary Wizards quickly let it cast mid-sized and then huge spells for free. Some of those Wizards double as mana sources or tutor their partners. (Baral, Chief of Compliance, Kaza, Roil Chaser, Alisaie Leveilleur) - Free-cast bombs: Expensive sorceries become free through Gandalf, Party Guest and stack further value by casting or copying other spells, taking extra turns, or adding combats. (Aminatou's Augury, Call Forth the Tempest, Time Warp) - Spellcast payoffs: Creatures and enchantments reward every instant or sorcery with cards, flying tokens, Treasure, burn and team pumps, which turns a spell chain into a board and a damage clock. (Talrand, Sky Summoner, Fiery Inscription, Jeskai Ascendancy) - Trigger doubling: Several pieces make Wizard or spell-cast triggers fire twice, multiplying the payoffs and even Gandalf, Party Guest's own combat trigger. (Veyran, Voice of Duality, Harmonic Prodigy, Wizard's Staff) - Copying and recursion: Spells get copied or recast from the graveyard to squeeze extra value from the best instants and sorceries. Narset's Reversal on Approach of the Second Sun returns the original to hand and copies it, setting up the alternate win. (Narset's Reversal, Alania, Divergent Storm, Lier, Disciple of the Drowned) - Counter suite and closers: Cheap counters protect the engine, while legendary-only sweepers, team evasion and mass pumps finish games through combat. (Urza's Ruinous Blast, Akroma's Will, Full Throttle)
