Overview:

A Grixis spellslinger deck helmed by Jeleva, Nephalia's Scourge that focuses on casting powerful instants and sorceries while leveraging wheel effects and card draw damage through cards like Nekusar, the Mindrazer.

Primer:

The deck operates on multiple axes, primarily focusing on casting big spells through Jeleva, Nephalia's Scourge's ability while also incorporating a wheel/card draw damage subtheme. The strategy involves setting up card advantage engines through enchantments like Rhystic Study and Mystic Remora, then leveraging powerful spells like Expropriate and Cruel Ultimatum for maximum impact.

The deck can win through various methods, including commander damage with Jeleva, spell copying with Thousand-Year Storm, or draining opponents through Nekusar, the Mindrazer and similar effects. The inclusion of numerous copy effects like Wild Ricochet and Dualcaster Mage allows for explosive turns where spells can be duplicated for massive value.

Weaknesses:

The deck is heavily reliant on its commander and expensive spells, making it vulnerable to targeted removal and counterspells. The mana base could be improved with more efficient rocks and lands. The deck can struggle against aggressive strategies that can apply pressure before the deck's engine gets online, and graveyard hate can shut down some of its recursion elements.

Attribute Ratings:

• Speed: 5/10
• Resilience: 4/10
• Consistency: 5/10
• Interaction: 6/10

Rating Justification:

This deck sits firmly in the focused casual range, showing more cohesion than a typical precon but lacking the explosive speed and consistency of higher-powered decks. While it contains some powerful cards like Expropriate and Cyclonic Rift, its reliance on expensive spells and somewhat clunky mana base keeps it from competing with more optimized builds. It would struggle against decks in the 6.0+ range due to their faster setup and more efficient interaction, but could hold its own against other casual decks through its powerful late-game plays.

Final power level rating: 5.0 - 5.5
