Oh right. Since u type ur question unclearly so I misunderstand. Anyway, if u want to do that, then use the Unit Event System by Bribe (If I remember it correctly) in the Spells Section. It can detect when a unit reincarnated. After that unit has reincarnate (which u can detect by the system I mention above), u can add it to a unit group, create a loop trigger to countdown until the cooldown of the Reincarnation spell is done, remove it from the unit group.
And u also need to trigger ur Resurrection spell. So that it will also revive any unit in that unit group.
