[Hearthstone] Deathrattle Mechanic

Ever wondered why your deathrattle sometimes proc first and sometimes proc last when your deathrattle minion and enemy deathrattle minion died at the same time? Here's the reason: Since Naxxramas update, if multiple minions are killed in same time, it's triggered in order from oldest played on board (played first) to newest. So, can you kill harvest golem and damaged golem produced by deathrattle with deathbite? yes, you can IF your deathbite summoned before the harvest golem. You also can take baine from cairne deathrattle with sylvanas IF enemy cairne summoned before sylvanas. Hope this explain a lot :D
