Damage ≠ kills: Grapeshot deals the most damage (3075) but Manamorphose gets the most kills (49). The closer and the damage engine are different cards — don't evaluate them the same way.

Speed shapes your closer: In fast matchups (T≤6) like Affinity, your Manamorphose closes. In grindy matchups (T≥8) like Goryo's Veng, Desperate Ritual takes over. Board differently for speed vs grind.

Sideboard asymmetry: vs 4c Omnath, G1 WR is 90% but match WR drops to 22% (-68pp). Opponent adapts better post-board.

Removal blind spot: Signal Pest from Affinity deals 89 damage and is likely outside your mainboard removal range. Consider SB answers for this axis.

Hidden damage engine: Goblin Token deals 820 total damage — a top source that doesn't appear in your decklist. Never board out the cards that produce these tokens.

Weighted gap -2.4pp: This deck underperforms at top tables vs the field. Struggles against popular decks — consider adapting your SB for the T1 field.
