Dauthi Horror

The redundant evasion clause is doing real design work, not flavor padding. Shadow already walls this creature off from nearly every blocker the game offers, restricting combat to the small subset of bodies that share the keyword. The rider stapling on "can't be blocked by white creatures" exists for the one matchup that breaks that logic: an opponent who has fielded their own shadow blockers. White, in the color pie of the era, was where the cheap defensive shadow bodies clustered, so this is a creature built with a specific evasion arms-race in mind. Even if the shadow mirror collapses into trading walls, this one keeps connecting against the color most likely to have something to interpose. It treats shadow not as a one-line keyword but as a real combat subsystem with counterplay, then writes a clause to pre-empt that counterplay from the one direction it could come from. The body is the rest of the statement: a 2/1 on a two-mana frame, all of it aimed at faces that cannot legally stand in the way. Shadow as a mechanic never returned in a meaningful way, which makes cards like this artifacts of a brief experiment in parallel-board evasion, where two armies could pass through each other untouched and the deck with the better unblockable clock simply won the race.
