Forbidding Watchtower

The white entry in the Urza's Legacy manland cycle, and the one whose body is built for attrition rather than tempo. The 1/5 frame is a tell: this is a land that wants to block, soak up an attacker, and survive the turn, not race in for damage. That defensive posture is the whole pitch. A control deck with no early threats still wants its lands to do something in the late game, and a manland that cannot be answered by sorcery-speed removal while it sits as a land is exactly the kind of inevitability-without-exposure that white control wants. The cost structure keeps it honest in two places: it enters tapped, so it never accelerates you, and the activation has to be paid every turn the threat is live, so it taxes your mana the way a stable body never would. That tax is the trade for a slot that otherwise produces only white mana. The cycle as a whole (a white-, blue-, black-, red-, or green-producing utility land that also fights) became one of the cleaner answers to the problem of board wipes: a card that survives a sweeper because it is a land when the wrath resolves, then climbs off the floor and starts attacking once the dust settles.
