The Commander

Menace

Whenever Obeka deals combat damage to a player, you get that many additional upkeep steps after this phase.

Guide

Gameplan

Connect with Obeka in combat to chain multiple extra upkeep steps, then exploit cards that trigger on your upkeep to snowball value, mana, or a loop into a kill. The deck is a Grixis combo-engine that uses pump and evasion to maximize the number of upkeeps generated, then converts those triggers into game-winning effects.

Strengths

Generates absurd amounts of upkeep triggers, letting you loop ETB-on-upkeep mana and draw engines
Menace makes Obeka hard to block, and pumping her power directly scales the payoff
Grixis colors give access to the best tutors, ramp, and interaction in the format
Can assemble compact two-card kills with the right upkeep payoffs

Weaknesses

Highly commander-dependent; without Obeka connecting the deck stalls
Vulnerable to spot removal, fog effects, and blockers that stop combat damage
Pump-and-swing plan can be slow and telegraphed against fast metas
Many upkeep payoffs are narrow build-arounds that are weak in isolation

Key Cards

Mortal Combat — With twelve creatures in your graveyard, every extra upkeep is a chance to win outright.
Mind's Dilation — Each upkeep step you can sculpt the loop, and it punishes opponents while you draw out turns.
Helm of the Host — Copies Obeka for redundant attackers, multiplying combat damage and upkeep generation.
Rampaging Ferocity — Cheap evasive pump that boosts Obeka's power so each hit yields more upkeeps.
Aetherflux Reservoir — Upkeep-triggered lifegain and recursion lets you loop into the 50-life laser kill.
Sword of Feast and Famine — Untaps your lands each combat and grants protection, fueling more spells across the extra upkeeps.

Upgrade Path

Add fast mana (Mana Crypt, Jeweled Lotus) and efficient tutors (Vampiric Tutor, Demonic Tutor) to find your upkeep payoff and the pump to connect. Tighten the curve with cheap evasion and protection so Obeka reliably hits turn five, and lean into a deterministic combo finish rather than relying on grindy value to avoid getting raced.

Win Conditions

▸Loop an upkeep payoff like Mortal Combat or Aetherflux Reservoir into a one-shot kill
▸Commander damage from a pumped, evasive Obeka (often doubled with Helm of the Host)
▸Snowball card and mana advantage across dozens of upkeeps until you out-resource the table
▸Drain or burn the table with stacked upkeep triggers like Sheoldred or Cruel Reality

Archetypes

Combo — Repeated upkeep steps let you loop upkeep-triggered payoffs into game-ending engines.
Voltron — Pumping and protecting Obeka to connect is itself a path to commander-damage kills.
Spellslinger — Extra upkeeps stack with cantrips and rituals to flood the board with mana and cards.
Group Slug/Chaos — Upkeep-based 'each player' effects and chaos enchantments compound brutally under Obeka.
