Rationale
Attuma is a 4cmc merfolk lord granting +1/+1 to all other Merfolk and drawing a card whenever one or more Merfolk attack a player — a powerful, efficient repeatable draw engine that rewards the natural Merfolk go-wide/attack plan. Signature commander or 99-card inclusion for any merfolk tribal deck; the attack-triggered draw scales well in Commander where you always have opponents to attack.
Learnings (3)
Attuma's draw trigger fires once per combat regardless of how many Merfolk attack simultaneously ("one or more"), meaning it rewards a wide board but doesn't chain multiple draws in one attack step.

The trigger requires attacking a player specifically, not a planeswalker — this distinction matters in planeswalker-heavy Brawl/Commander games where a player may redirect attacks.
tagging · claude-sonnet-4-6
Because Attuma only buffs OTHER Merfolk (not himself), he is a 3/4 for 4 in a vacuum — his value is entirely dependent on a Merfolk-dense board, making him weak if removed repeatedly.
