Phyrexian Censor

White has a long history of taxing effects that slow the game to a crawl, but this one asks a sharper question: what happens when the tax has a loophole only your side is built to exploit? The one-non-Phyrexian-spell-per-turn clamp is a symmetrical Arcane Laboratory, the kind of resource lock that punishes any deck trying to chain spells into a turn. The twist is that Phyrexian spells are exempt from the count, so a deck stacked with the compleated and the mechanical can keep casting while the opponent is throttled to one. The tapped-entry rider on non-Phyrexian creatures does the same asymmetric work in combat: your Phyrexians arrive untapped and ready to block, everyone else's arrive vulnerable and a turn behind on tempo. Read together, the two abilities describe a hatebear built for a specific creature type rather than a specific strategy, which is unusual. Most stax pieces are color- or spell-type-hostile; this one is tribe-hostile, and it rewards you for the metal you brought rather than the plan you drew. And because the lock rides on a 3/3, the card doesn't sit inert waiting for the disparity to pay off: it applies pressure while it taxes, closing the game on the same clock that grinds the opponent down to a single spell each turn.
