Exalted Flamer of Tzeentch

Two abilities point the same way and reward the same building block: instant and sorcery spells, cast and recast. Fire of Tzeentch turns every one of them into a Pestilence-lite ping to the whole table, so a spellslinger deck's normal churn quietly becomes a clock. Sorcerous Inspiration then closes the loop on the resource side, feeding a random instant or sorcery back from the graveyard each upkeep so the churn does not run dry. The randomness is the honest part of the design: you do not get to pick the burn spell or the ritual you most want back, which keeps the recursion from becoming a deterministic engine and asks the builder to run enough redundant cheap spells that any return is playable. A 2/4 body backs this up as a wall that survives the incidental combat while the noncreature-spell density does the actual work, rather than as a threat that wants to attack. What makes it more than a typical Izzet payoff is the direction of the damage: it does not care about your storm count or a single big spell, it cares about volume across the whole game, and it hits each opponent every time. That axis (many small spells, many small pings, recurred fuel to keep the count climbing) is the multiplayer expression of the spells-matter archetype, built for a table where three or four life totals erode a point at a time.
