Overview:

This is a highly optimized K'rrik, Son of Yawgmoth combo deck that aims to win through storm counts, life drain effects, or Aetherflux Reservoir, utilizing K'rrik's Phyrexian mana ability to chain multiple spells efficiently and generate massive card advantage through life-payment effects.

Primer:

The deck operates primarily as a fast combo deck, leveraging K'rrik, Son of Yawgmoth's ability to pay life instead of black mana to chain multiple spells together. The primary game plan involves quickly deploying K'rrik and using powerful card draw engines like Necropotence, Ad Nauseam, or Bolas's Citadel to dig through the deck while generating mana through rituals and fast mana artifacts. The deck can win through multiple paths, including storm count with Tendrils of Agony, Aetherflux Reservoir, or large Exsanguinate plays.

The deck is built with exceptional consistency, featuring numerous tutors and efficient card selection tools. The reanimation package serves as both a backup plan and a way to recover key pieces. The deck can frequently attempt wins as early as turn 2-3 with protection, utilizing cards like Chrome Mox, Lion's Eye Diamond, and various ritual effects to generate explosive turns. The inclusion of interaction pieces like Opposition Agent and Dauthi Voidwalker allows the deck to disrupt opponents while assembling its combo pieces.

Weaknesses:

• Highly vulnerable to graveyard hate and life gain prevention effects
• Susceptible to commander-specific removal, as K'rrik is crucial to the strategy
• Can be disrupted by effects that prevent life payment or life loss
• Weak to artifact removal due to reliance on fast mana and combo pieces

Rating Justification:

This deck consistently threatens wins by turn 2-3 with protection, placing it firmly in the cEDH category. The extensive tutor suite, fast mana package, and multiple win conditions make it highly consistent and resilient. While not quite at the absolute top tier of cEDH decks, it's capable of competing at the highest levels and can regularly establish game-winning positions by turn 2-3 with protection.

Final power level rating: 9.0 - 9.3

The deck demonstrates all the hallmarks of a competitive EDH deck, including efficient tutors, fast mana, multiple compact win conditions, and relevant interaction. While it may not be as explosively fast as some tier 1 cEDH decks, its consistency and resilience make it a formidable competitor at high-powered tables.
