Mek'leth Berserker

Four mana for only a 4/3 menace is far below Modern's rate and provides no immediate value, interaction, or synergy.

Could be wrong if An unrevealed Klingon or creature-matters shell could create an unusually efficient home.

A vanilla four-mana combat creature is much too slow for Legacy and compares poorly with its efficient threats and free interaction.

Could be wrong if Unexpected tribal support could matter, though the standalone rate remains extremely poor.

Menace makes combat awkward, but a four-mana creature without an ETB effect trails Pauper's efficient threats and value engines.

Could be wrong if A slow, creature-heavy red shell could want it as a curve-topper, but no such support is supplied.

A 4/3 menace offers only combat damage and no multiplayer scaling, card advantage, mana, or meaningful tribal support.

Could be wrong if Future Klingon tribal density could provide a narrow home not visible in the supplied context.

A four-mana 4/3 with menace pressures life totals and can force unfavorable double-blocks, making it a reliable main-deck creature.

Could be wrong if Unknown removal density, speed, and archetypes could make its three toughness or four-mana cost less effective.
