Overview:

This 5-color legendary-focused deck leverages Jodah, the Unifier to create massive value through legendary cascades and board buffs. The strategy revolves around explosive ramp into game-ending Ultimatums or overwhelming legendary creature synergies, supported by land destruction locks and efficient interaction.

Primer:

Core Strategy:
This deck aims to cast Jodah by T3-4 using premium ramp (Bloom Tender, Delighted Halfling), then chain cascades into powerful legends like Sisay, Weatherlight Captain and Yidris, Maelstrom Wielder. Alternate win paths include:

1. Ultimatum Bombing: Casting Emergent Ultimatum/Ruinous Ultimatum with cascades
2. Legendary Swarm: Overwhelming combat damage via Jodah's exponential +X/+X scaling
3. Resource Denial: Pairing Armageddon/Obliterate with mana rocks/indestructible lands

Mulligan Priorities:

• 3 lands (ideally untapped duals)
• 1-2 ramp pieces (Sol Ring, Faeburrow Elder)
• At least 1 legendary creature or protection spell
  Reject hands without early mana acceleration or color fixing.

Key Tips:

• Sequence cascades carefully: Cast lower MV legends first to maximize Jodah triggers
• Use Teferi's Protection/Galadriel's Dismissal to protect during land destruction turns
• Tutor priorities: Chromatic Orrery for mana, Primevals' Glorious Rebirth for recovery

Avoid Traps:

• Don't overextend into board wipes before establishing recursion
• Save counterspells for key stax pieces rather than midrange threats

Weaknesses:

Critical:

• Heavy reliance on Jodah - 3+ removals cripples the strategy
• Weak to Drannith Magistrate/Containment Priest shutting off cascades

Moderate:

• Slow recovery from mass artifact destruction
• Limited graveyard hate for opposing combos

Minor:

• Some tapped lands slow early turns
• High MV spells vulnerable to early counters

Most Important Cards:

• Chromatic Orrery
• Leyline of the Guildpact
• Primevals' Glorious Rebirth
• Emergent Ultimatum
• Sisay, Weatherlight Captain
• Faeburrow Elder
• Teferi's Protection
• Demonic Tutor
• Exquisite Blood
• Armageddon

Attribute Ratings:

Speed: 7/10
Can deploy Jodah + cascade engine by T3 with optimal hands, threatening Ultimatum wins by T6. Land destruction creates T5-6 effective wins.

Resilience: 6/10
12 counterspells and protection effects, but over-reliance on Jodah. Recursion via Primevals' Glorious Rebirth helps recover.

Consistency: 8/10
14 tutors + Jodah's cascade ensure legendary density. Mana base supports 5-color needs through rocks and duals.

Interaction: 7/10
Efficient removal (Swords to Plowshares) and free counters (Fierce Guardianship absent, but Force of Negation-like effects present). Lacks board wipes beyond land destruction.

Rating Justification:

The deck sits between "Focused Competitive" (T5-6 wins) and "Optimized" (T6-7) due to:

• Faster than T7-8 "Focused" decks via cascade chains
• Less consistent than T5 cEDH with no infinite combos
• Stax elements (land destruction) create T5-6 effective wins
• Protection suite matches 6.5-7.0 resilience expectations

Power level: 6.5 - 7.0
