Gideon's Lawkeeper

A repeatable tapper at one mana, which is the whole pitch: this is the white control deck's blocker that doesn't block, the body that neutralizes an attacker every turn without ever leaving the ground. The lineage runs back through Master Decoy and a long line of cheap white creatures whose job is to pacify the biggest thing on the other side of the board. What separates this iteration from the old tappers is the rate: a one-drop body means the effect comes online a turn earlier than the classic two-mana versions, and a Human Soldier on a 1/1 frame slots into the kind of weenie shells that already wanted both the tribe and the cheap clock. The activation cost (a mana plus the tap) keeps it honest by gating it to once per turn and demanding open white, but the function compounds: point it at a blocker to push damage through, or at an attacker to fog the swing, and the same card swings between offense and defense depending on what the turn needs. It is a soft lock when paired with anything that untaps it or removes summoning sickness, but even at baseline, the threat of activation reshapes how the opponent attacks and blocks. Small body, modest text, but the kind of tempo lever that has quietly defined white's interaction below the level of removal spells for the entire history of the color.
