Greenside Watcher taps to untap a Gate you control — repeatable pseudo-ramp that turns every Gate into a mana source if you can abuse the tap ability. Outside of dedicated Gate synergy decks built around Nine-Fingers Keene, it does nothing.

Nine-Fingers Keene
Nine-Fingers Keene rewards you for running a Gate-heavy manabase, and Greenside Watcher converts that base into an engine — untapping Gates to reuse landfall triggers, filter mana, or accelerate into Keene's activated ability turn after turn.

Greenside Watcher is a Commander card, full stop. In the Nine-Fingers Keene archetype it earns its slot by untapping Gates repeatedly, which translates to real mana and landfall abuse in a shell already built around that land type. In every other format — Modern, Pioneer, Pauper, Legacy — there is no Gate engine worth supporting, so Greenside Watcher sits unplayed. It's legal across the board, but legality and playability are different things here.

$0.07 bulk tier
At $0.07, Greenside Watcher is deep bulk — grab a copy at the bottom of any common box without a second thought. Demand is narrow enough that the price won't move meaningfully in either direction.
