Take into Custody

In Commander, Take into Custody is a precision tool: you tap down a general swinging for lethal, or lock out an opponent's combo piece for a full turn cycle, which is long enough to matter. Pauper is where it sees the most competitive consideration, fitting naturally into tempo and control shells that want cheap interaction without spending card equity on a kill spell. In Modern and Pioneer, one-mana tap effects compete with counterspells and hard removal, so Take into Custody rarely makes the cut outside of specific flicker or untap synergies. Legacy and Vintage move too fast for a tap effect to do meaningful work.
