Neerdiv, Devious Diver

—

Neerdiv is a 3cmc legendary Merfolk Rogue that mills equal to its power whenever it becomes tapped (including attacking, tap abilities, etc.) and draws a card + grows whenever you cast/activate from the graveyard. Its two triggers create a synergy loop: mill to fill the graveyard, then exploit the graveyard to grow Neerdiv and draw, which mills more. It's a build-around commander or 99-card piece in self-mill / graveyard-matters shells, but is fragile, starts small at 2/2, and does little without a graveyard engine already online.

• Neerdiv's tap trigger fires whenever it becomes tapped by ANY means — attacking, tap abilities from equipment or other permanents, or opponent's Icy Manipulator effects — giving it unusual synergy with untap-and-retap loops for repeated milling.

• The second trigger rewards both casting spells FROM the graveyard (flashback, escape, unearth, etc.) AND activating abilities of cards IN the graveyard (cycling activation, channel, etc.), making it subtly broader than a pure flashback payoff.

• As a commander, Neerdiv's mill scales with its own power, so a single +1/+1 counter doubles the base mill rate — early counter production from a single graveyard activation meaningfully accelerates the mill clock.
