Character Background

Devastating Onslaught reads like a red finisher that best supports a tempo/combo game plan: you pay into X to flood the board with haste copies and either punch through for lethal or chain triggers for a one-turn avalanche of value. It’s ideal in decks that want ephemeral board presence—copy a creature with a juicy ETB or combat-damage trigger and swing immediately, or copy an artifact creature that taps for mana and then sacrifice it. Specific synergies include Panharmonicon to multiply ETB triggers, and sac outlets like Ashnod’s Altar or Altar of Dementia to convert the tokens into mana, milling, or sacrifice-trigger value before they vanish at end step. Deckbuilding notes: avoid targeting legendary creatures (commander rule/state-based effects can kill duplicates), include rituals or artifact mana to pay big X reliably, and favor non-legendary, high-impact targets with on-hit or ETB effects so the ephemeral tokens turn into immediate, repeatable advantage rather than wasted bodies.
