The second ability includes your own creatures as well. [Barclay 1998/06/10]
It dies as a state based effect just after you remove the last counter when announcing its ability to remove a counter and right before any other spells or abilities can be used. There is no way to sacrifice it or do anything else with it before it dies. [D'Angelo 1999/06/01]
