Cards

The real card

Prevent all damage that would be dealt to Sevinne. Whenever you cast your first instant or sorcery spell from your graveyard each turn, copy that spell. You may choose new targets for the copy.

Two things matter and the printed text confirms the scout’s read: (1) Sevinne is damage-proof, so she walls aggro and survives her own sweepers; (2) the copy trigger only fires on the first instant/sorcery you cast from your graveyard each turn — NOT from hand. So the deck is built specifically around recasting spells out of the yard: flashback, retrace, and jump-start. Cast a flashback burn spell from the graveyard, Sevinne copies it for free — every recursion is a two-for-one.

commander_oracle_ok = true — built around the real ability.

Gameplan

Draw-go control that wins on inevitability, not on a single wrath. Trade your hand spells one-for-one early, fill the graveyard, then start grinding: every turn you recast one flashback/retrace/jump-start spell from the yard and Sevinne doubles it. Doubled removal keeps the board clear; doubled card draw refills; doubled burn (Chain Lightning, Firebolt, Scorching Missile, Direct Current) chips faces. Sevinne being damage-proof means you can sit behind her indefinitely while the engine buries the table.

Key synergy lines

  • Flashback burn + Sevinne = double removal/reach. Firebolt flashback → copy = 4 to the dome or two kills. Geistflame/Lava Dart recast pings twice. Scorching Missile flashback copied = 8 to a face.
  • Retrace loop. Flame Jab (retrace, ) and Oona’s Grace (retrace card draw) recast every turn by discarding excess lands — each one is the “first graveyard cast,” so each gets copied. Flame Jab becomes a repeatable doubled pinger; Oona’s Grace a repeatable doubled cantrip.
  • Erebor Flamesmith is the inevitability clock: it triggers “whenever you cast an instant or sorcery,” and every flashback/retrace recast from the yard is a cast — pinging each opponent. Festival Crasher / Kiln Fiend / Eager First-Year turn the same spell-density into evasive-ish beatdown.
  • Pseudo-wipe that loves Sevinne. Sulfurous Blast flashback… it has no flashback, but it’s an instant you can hold; the real recurring sweeps are Boiling Earth / Scouring Sands (1 to each opponent’s board) — cheap, and copies stack damage. Sulfurous Blast (2 to each creature + each player, 3 on your main phase) is the hard reset that Sevinne survives.
  • Finishers. Battle Screech (token flood, its own flashback makes 4 fliers total), Seize the Storm (an Elemental sized by instants/sorceries in yard — huge in this deck), Retrieve the Esper (3/3, +2 counters when cast from yard), and doubled burn close.

Role breakdown (with counts)

  • Lands — 37. (High end for three colors.)
  • Ramp / mana rocks — 9: Sol Ring, Mind Stone, Prophetic Prism, Manalith, Commander’s Sphere, Mana Cylix, Wayfarer’s Bauble, Star Compass, Arcum’s Astrolabe. (7 of these fix colors.)
  • Card advantage / draw — 10: Think Twice, Deep Analysis, Desperate Ravings, Electric Revelation, Radical Idea, Scour All Possibilities, Secrets of the Key, Otherworldly Gaze, Faithless Looting, Pursue the Past. (Most have flashback/jump-start = Sevinne fuel.)
  • Spot removal / interaction — 11: Firebolt, Geistflame, Flame Jab, Lava Dart, Chain Lightning, Burst Lightning, Galvanic Blast, Tome Blast, Direct Current, Scorching Missile, Sonic Assault — plus white removal Guiding Bolt, Radiant’s Judgment, Reprisal, Destroy Evil, Skywhaler’s Shot, and bounce Silent Departure / Grasp of Phantoms / Dematerialize. (Counts the burn package as flexible removal-or-reach; total interactive spells well above 11.)
  • Counters — 6: Condescend, Mana Leak, Negate, Force Spike, Dispel, Izzet Charm.
  • Mass / pseudo-wipe — 3: Boiling Earth, Scouring Sands, Sulfurous Blast.
  • Payoffs / engine / finishers — remainder: Erebor Flamesmith, Festival Crasher, Kiln Fiend, Eager First-Year, Faerie Seer, Battle Screech, Rally the Peasants, Seize the Storm, Retrieve the Esper, Pirate’s Pillage, Gravitic Punch, Cenn’s Enlistment, blink (Momentary Blink / Ephemerate).

Manabase / fixing note

37 lands: Command Tower, Crystal Grotto, Painted Bluffs, Perilous Landscape (Jeskai basic-fetch), Ash Barrens, all three guildgates + their bounce/tap duals (Tranquil Cove, Wind-Scarred Crag, Swiftwater Cliffs, Meandering River, Highland Lake, Stone Quarry), five cycling deserts/lands, and 6/6/6 basics — plus 7 color-fixing rocks for ~19 total fixing sources, comfortably casting on curve.

Pilot notes

  • Mulligan for fixing + a graveyard-enabler. You want Sevinne online turn 4–5 and a flashback/retrace spell in the yard to start the copy loop.
  • Sequence the copy: each turn cast your best graveyard spell first (that’s the one Sevinne doubles). Hold cheap flashback pingers to bait, copy the big removal/burn.
  • Sevinne is damage-proof, not indestructible — watch for edicts, -X/-X, and exile. Keep a counter up against targeted removal.
  • Flame Jab + Oona’s Grace are your turn-after-turn engine when flooding on lands; discard the extra lands to retrace.

Weaknesses

  • Light on hard creature removal at common — relies on burn (toughness-capped) and bounce for fatties; Reprisal/Radiant’s/Skywhaler’s only hit big creatures. Indestructible/high-toughness threats are awkward.
  • Graveyard hate (exile-on-cast, yard wipes) shuts off the whole engine.
  • Slower to close than the table can be — needs Erebor Flamesmith or token finishers to actually convert the grind into lethal.
