Grizzled Angler // Grisly Anglerfish

The flip condition is the whole design conceit: a self-mill creature whose payoff for digging is finding something monstrous in the dirt and then becoming it. Tapping mills two and, during resolution, checks the graveyard for a colorless creature card, which in the era this design emerged meant the Eldrazi, so the activated ability encodes a tiny narrative (a fisherman hauling up something that should not exist) directly into its mechanics rather than leaving the flavor to the art alone. The front does more work each turn than a 2/3 suggests, because the ability costs only a tap: every activation both advances the transform clock and feeds your own yard, so even a board it cannot meaningfully block is steadily filling your graveyard and pulling the Anglerfish closer. The transformation is one-way (once Grisly Anglerfish arrives it stays), which is what lets the back side trade the fisherman's tackle for a mass-goad engine: paying six forces every creature your opponents control to attack this turn if able. That does not herd them into the Anglerfish (it dictates that they swing, not where); it empties the defenders' side and pries open a stalled board. The friction lives in the timing, because the two faces want opposite battlefields. You flip fastest by tapping across early turns at no mana cost, but the goad only bites once your opponents have committed boards worth emptying, so the transform must be spent before the situation that rewards it has formed.
