Matoc, Lavamancer

Modern's speed and efficient removal make a four-mana 2/3 with no immediate effect a poor fit; the activated ability is too mana- and graveyard-intensive.

Could be wrong if An unusually dense two-damage synergy shell may test it, though no supplied established home supports that outcome.

Four mana for a fragile value creature is far below Legacy's efficiency threshold, and neither ability supplies immediate interaction or a unique engine.

Could be wrong if The score rises only if a specialized exact-two damage combo or engine proves resilient enough for Legacy.

Damage decks can turn repeated exactly-two hits into meaningful impulse cards, while Matoc's activation supplies removal and its own trigger; four mana and fragility limit breadth.

Could be wrong if It may prove too slow and conditional versus broader red card-advantage engines, especially without sufficient two-damage density.

A 2/3 is modest, but Matoc can repeatedly turn two-power combat or its own 2-damage activation into cards and eventually control small creatures.

Could be wrong if Unknown removal, speed, and archetype support could leave a four-mana 2/3 too slow or make exactly-two triggers infrequent.
