How it grades
Fundamentals 75/100. Plays like Dragon Tribal and Tokens.
This reads as Dragon Tribal · Tokens, built around The Ur-Dragon. A Dragon deck at heart: the creatures share a type on purpose, and lords, payoffs, and type-matters synergies make the whole board bigger than its parts. Tribal decks trade individual card power for critical mass, so keep the dragon count high and let the synergy pay the bills. Its strongest fundamental is land count (35 lands. About 36 fits this curve for Dragon Tribal, with your cost reduction counted); the first thing to tighten is card draw: 5 draw effects (want 10+ for Dragon Tribal).

Where it falls short
- B+Mana reliability83% of your spells arrive on time. Scourge of Valkas is the riskiest: its R cost is heavy for this mana base, so expect it several turns late.
- CCard draw5 draw effects (want 10+ for Dragon Tribal).
Strong on land count, mana curve, ramp, interaction, commander synergy, win conditions, card quality and legality & size.
