If there is more than one Captured by the Consulate on the battlefield, the triggered ability of each one will change the target if able. The last one to resolve determines what that spell finally targets. If one player controls more than one Capture by the Consulate, they choose the order in which they resolve. If multiple players control those Auras, the first player among them in turn order (starting with the player whose turn it is now) is the one whose triggered ability resolves last.
