How it grades
Fundamentals 80/100. Plays like Lands-matter and Reanimator / graveyard.
This reads as Lands-matter · Reanimator / graveyard, built around The Necrobloom. Lands are the engine, not the tax: extra land drops and landfall triggers turn every land into ramp, bodies, and card advantage at once. The land count runs deliberately high, recursion makes fetches replayable, and the late game wins through land-fueled payoffs the table can't interact with easily. The Necrobloom sits on the cEDH tier list, so the ceiling here is tournament-grade, and experienced tables will treat it that way. Its strongest fundamental is mana curve (35% of spells cost ≤2, 12% cost 6+); the first thing to tighten is card draw: 6 draw effects (want 10+ for Lands-matter).

Where it falls short
- B+Land count39 lands. About 42 fits this curve for Lands-matter.
- C+Card draw6 draw effects (want 10+ for Lands-matter).
- B+Interaction8 removal/protection effects (want 10+ for Lands-matter).
Strong on mana reliability, mana curve, ramp, commander synergy, win conditions, card quality and legality & size.
