Overview:

This is a high-powered storm/spellslinger deck that aims to chain together powerful instants and sorceries, utilizing cost reduction and spell copying effects to generate massive value or achieve storm-based wins through cards like Brain Freeze and Grapeshot.

Primer:

The deck operates primarily as a storm combo deck, using Jeleva, Nephalia's Scourge as both a value engine and potential combo piece. The strategy revolves around generating massive amounts of mana through cards like High Tide, Dark Ritual, and fast mana artifacts, then chaining together spells with cost reduction effects and spell copying. The deck can win through traditional storm counts with Brain Freeze or Grapeshot, or through powerful value plays like Expropriate and Peer into the Abyss.

The deck's execution typically involves careful resource management in the early game, using efficient counterspells and card draw to set up for explosive turns. Key pieces include Underworld Breach, Past in Flames, and Yawgmoth's Will for recursion, while Thousand-Year Storm and Bonus Round act as spell multipliers. The deck can often win as early as turn 3-4 with the right opening hand, particularly through lines involving Lion's Eye Diamond and Underworld Breach.

Weaknesses:

• Vulnerable to graveyard hate like Rest in Peace which shuts down many recursion lines
• Can be disrupted by targeted removal of key enchantments like Thousand-Year Storm
• Susceptible to stack interaction and counter-magic wars
• Can struggle if the commander is repeatedly removed due to commander tax

Most Important Cards:

1. Underworld Breach
2. Lion's Eye Diamond
3. Yawgmoth's Will
4. Past in Flames
5. Brain Freeze
6. Thousand-Year Storm
7. Dark Ritual
8. Mana Drain
9. Force of Will
10. Demonic Tutor

Attribute Ratings:

• Speed: 9/10
• Resilience: 8/10
• Consistency: 9/10
• Interaction: 9/10

Rating Justification:

This deck consistently threatens wins by turn 3-4 and can occasionally achieve turn 2 wins with perfect hands. The high density of tutors, fast mana, and protection pieces puts it firmly in cEDH territory. While not quite at the absolute highest tier of cEDH decks, it's extremely powerful and can compete at the highest tables. The inclusion of multiple win conditions and strong protection suite makes it more resilient than typical storm decks.

Final power level rating: 9.0 - 9.3

The deck shows all hallmarks of a competitive EDH deck: efficient mana base, strong interaction suite, multiple compact win conditions, and the ability to consistently threaten early wins. While it doesn't quite reach the highest tier of cEDH decks that can consistently threaten turn 1-2 wins, it's definitely a strong competitive deck capable of competing at high-powered tables.
