M4 Boros Storm 86%

M4 Boros Storm is a red-white (Boros) spells/storm-style midrange-combo deck in Standard. It looks to chain together cheap instants, sorceries, and value permanents to build momentum, trigger payoff creatures, and generate explosive turns.

Its core game plan is to use cards like Slickshot Show-Off, Emberheart Challenger, and Quintorius Kand as payoff threats while burn and interaction such as Burst Lightning and Death to Our Enemies clear the way. Cards like Pursue the Past, Tablet of Discovery, and Improvisation Capstone help keep spells flowing, while sweepers like Day of Judgment and Avengers Disassembled let it reset the board when behind.

The deck generally wins by assembling a high-tempo spell chain, pressuring with evasive or scaling threats, and finishing the opponent with combat damage plus burn after a big value turn.
