This is a Jeskai spellslinger deck built to cast two or more spells every turn. Shiko and Narset copies the second spell each turn when it targets a permanent or player, and draws a card when it doesn't. Cost reducers, cheap cantrips, treasure and free-cast effects let the deck chain spells. Cast triggers turn that chain into tokens, burn, card draw and copies, and flashback and spell copying stretch it further. How it wins: Repeated cast triggers build a wide board of prowess Monks, Elementals and Dragon Illusions, and pings drain opponents, so a big spell turn ends either in a lethal alpha strike or in burn straight to the face. Key roles: - Second-spell chaining: Cheap cantrips and mana reducers make it easy to hit Shiko and Narset's Flurry every turn. Targeted draw spells such as "target player draws" get copied, and untargeted ones still draw a card off the commander. (Goblin Electromancer, Haughty Djinn, Frantic Search) - Copy and trigger doubling: Effects that copy spells or double cast triggers multiply every targeted spell and every magecraft payoff alongside the commander. (Veyran, Voice of Duality, Narset's Reversal, Adaptive Training Post) - Free casting and flashback: These cards cast spells without paying mana or let instants and sorceries be recast from the graveyard, which extends one turn into a long spell chain. (Lier, Disciple of the Drowned, Baral and Kari Zev, Will of the Jeskai) - Token army from casting: Each noncreature or second spell creates bodies, from growing Monk swarms to hasty Dragon Illusions, and these become the main combat threat. (Monastery Mentor, Aligned Heart, Manaform Hellkite) - Burn and spell damage: Cast triggers deal direct damage to opponents, so a long chain can kill without combat. (Guttersnipe, Caldera Pyremaw, Electrodominance) - Card and mana engines: Draw-per-spell and treasure-per-spell permanents keep fuel and mana flowing so the chain doesn't stall.
