Goblin Assault Team — ruling 1

If Goblin Assault Team and another creature you control die simultaneously (perhaps because they were both dealt lethal damage in combat), the other creature won’t be on the battlefield when you choose a target for Goblin Assault Team’s ability. That creature can’t be saved by the +1/+1 counter that Goblin Assault Team gives.
