Planesmeld

Planesmeld has no controller. When Planesmeld enters the battlefield, all players put all land cards they control into the middle of the battlefield. All players may use this land, and it untaps during each player's untap step. While Planesmeld is on the battlefield, players cannot cast spells or activate abilities that would target opponents or any permanents or planeswalkers opponents control (including passive abilities). When Planesmeld leaves the battlefield, all land in the middle is exiled.
