A 0/4 that wins through other people's graveyards: its damage clock scales with the opponent's graveyard, not its own board, which inverts the usual problem with an unblockable beater. Most evasive threats need to be big to matter; this one needs the defending player to have done something. By the time a fair game has resolved a dozen spells, cracked some fetches, and traded creatures, the unblocked attack reads as a Lava Axe that only gets larger. The Fear keyword is what makes the trigger reliably live: in a graveyard-heavy era it slips past nearly everything that isn't black or an artifact creature, so the math the card threatens is the math it usually collects. The design tension is the body. Nothing about a 0/4 frame says "win condition," and that is precisely the disguise: it survives the burn and small creatures that would answer a real threat, then ends the game over a few turns of attacks that the opponent's own card advantage has loaded for it. It is a punisher card aimed squarely at decks that grind, mill, or recur, the ones that fill a graveyard as a matter of course. Against an empty graveyard it does nothing; against a long game it does everything. The card is built to make the second condition the common one.
