How it grades
Fundamentals 69/100.
No single established archetype dominates. This is its own brew around Derevi, Empyrial Tactician, so the fundamentals below carry the grade. Derevi, Empyrial Tactician 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 land count (38 lands. About 40 fits this curve); the first thing to tighten is card draw: 4 draw effects (want 10+).
- A-Mana reliability
- A+Land count
- A-Mana curve
- ARamp
- DCard draw
- A+Interaction
- BCommander synergy
- AWin conditions
- B-Card quality
- A+Legality & size
Where it falls short
- DCard draw4 draw effects (want 10+).
- BCommander synergyOnly 29 of 61 spells play into your commanders' plan; they want enters-the-battlefield support. Counts the builds players run with your commanders (Blink, Tokens; from EDHREC).
- B-Card qualityMedian EDHREC rank #9,848
Strong on mana reliability, land count, mana curve, ramp, interaction, win conditions and legality & size.
91 cards graded: A- 4, B+ 18, B 46, B- 10, C+ 5, C 2, C- 5, D 1. The command zone is the plan, so it isn't graded.
