Omnath, Locus of the Roil — Legendary Creature — Elemental (4/4)

When Omnath enters, it deals damage to any target equal to the number of Elementals you control. Landfall — Whenever a land you control enters, put a +1/+1 counter on target Elemental you control. If you control eight or more lands, draw a card.

Oracle note / discrepancy: the scout’s brief said Omnath “draws when a 4-power Elemental lands.” That is WRONG. The printed card draws when you control eight or more lands (any landfall trigger checks it), and the landfall counter targets an Elemental — not contingent on power. The build is therefore around (a) being an Elemental so the +1/+1 counters always have a home, (b) flooding lands to hit 8+ and turn every landfall into a cantrip, and (c) using the ETB ping as removal/reach. commander_oracle_ok = true.

Gameplan

Proactive Temur ramp. Chase 8+ lands fast with green land-fetch (most of which puts lands onto the battlefield, double-dipping landfall). Once Omnath is out with 8+ lands, every fetch/drop is “land + counter + draw a card” — a self-sustaining advantage engine. Counters pile onto Omnath or a landfall beater; the ETB ping (recast Omnath after a bounce/death, or just on first cast with a couple Elementals out) snipes blockers or chunks a face. Close with a wide-and-tall Elemental board, landfall pumps swinging through, and incidental reach from Cosi’s Ravager / Witty Roastmaster / Enraged Flamecaster.

Key synergy lines

  • Harrow / Springbloom Druid / Skyshroud Claim put multiple untapped lands in at once → multiple landfall triggers in one cast → multiple counters + multiple draws (at 8+ lands).
  • Stone-Seeder Hierophant untaps a land each landfall and can untap a land on demand — with a land-drop in hand that’s effectively an extra mana, and it untaps itself every trigger.
  • Sporemound turns every land into a 1/1 Saproling; Cosi’s Ravager turns every land into a Shock to the face — both snowball with the ramp.
  • Boiling Earth / Scouring Sands are one-sided sweeps (1 dmg to each opponent creature); my board, swollen with Omnath counters, shrugs them off while clearing tokens and mana-dorks.
  • ETB ping scales: bounce Omnath with Into the Roil / Blink of an Eye and recast for a bigger ping once the Elemental count is up.

Role breakdown (with counts — counted from the actual list)

  • Lands: 37 — 20 nonbasic (heavy 3-color fixing) + 17 basics.
  • Ramp: 11 core — Sakura-Tribe Elder, Sakura-Tribe Scout, Arboreal Grazer, Rampant Growth, Cultivate, Kodama’s Reach, Harrow, Search for Tomorrow, Springbloom Druid, Growth Spiral, Skyshroud Claim. (Plus Wayfarer’s Bauble, Fertilid, Embodiment of Spring, Leafkin Druid, Llanowar Visionary, Smokebraider, Prophetic Prism, Commander’s Sphere as additional fixing-ramp.)
  • Card advantage: 10 — Cloudkin Seer, Mulldrifter, Preordain, Serum Visions, Ponder, Frantic Inventory, Thrill of Possibility, Reckless Impulse, Big Score, Llanowar Empath. (Omnath himself + landfall is the real engine.)
  • Spot removal / interaction: 11 — Lightning Bolt, Burst Lightning, Galvanic Blast, Frost Bite, Flame Slash, Jaya’s Greeting, Lightning Strike, Voyage’s End, Into the Roil, Blink of an Eye, plus the counter suite (Counterspell, Negate, Essence Scatter) — listing the 8 burn/bounce + 3 counters.
  • Mass / pseudo-wipe: 2 — Boiling Earth, Scouring Sands (one-sided 1-damage sweeps).
  • Landfall / Elemental payoffs & beaters (rest): Omnath, Cosi’s Ravager, Sporemound, Stone-Seeder Hierophant, Valakut Predator, Wave-Wing Elemental, Akoum Hellhound, Snapping Gnarlid, Plated Geopede, Grazing Gladehart, Territorial Baloth, Ivy Elemental, Adventuring Gear, Groundswell, Khalni Heart Expedition, Pulse of Murasa, Enraged Flamecaster, Witty Roastmaster, Spitfire Lagac.

Manabase / fixing note

~17–19 fixing sources before basics: Command Tower, Path of Ancestry, Crystal Grotto, Conduit Pylons, Painted Bluffs, Shimmering Grotto, Bountiful Landscape (URG triome-fetch), three guildgates + six dual taplands covering all of UR/RG/UG, plus fetch-ramp (Cultivate/Kodama’s/Harrow/Rampant Growth/etc.) and rainbow rocks (Prophetic Prism, Commander’s Sphere, Smokebraider). No common dual taps an arbitrary pair on demand, so every pair is covered by gates/taplands and basics are reachable by the green fetch package.

Pilot notes

  • Mulligan toward at least one green source + a ramp spell; the deck wants to be dropping its second land-per-turn by mid-game.
  • Don’t over-commit Omnath into open mana — he’s your engine; recast value comes from the ETB ping, so a bounce-and-replay is fine, but respect counterspells.
  • Sequence landfall: with 8+ lands, crack fetches/Evolving Wilds after Omnath resolves so each fetched land draws you a card.
  • Save Boiling Earth/Scouring Sands for token boards or to break a go-wide aggro start; they’re asymmetric in your favor.

Weaknesses

  • Light on hard interaction beyond burn/bounce; big single threats (indestructible / high-toughness) dodge the burn package — lean on bounce and counters.
  • No true board wipe at common; a resolved wide go-tall board from an opponent can outrace if you stumble on ramp.
  • Graveyard/recursion is thin (only Pulse of Murasa); a removal-heavy table can grind the Elemental board down.
