If you play a leeroy Jenkins and your opponent has a knife juggler your oppoent will be awarded the two 1-1 whelps before you can attack with leeroy, the whelps trigger 2 knife juggles which may kill your leeroy immediately.

At least he had chicken! (Or whatever the fuck he says)

And yes I have been there done that (my Leeroy got killed)

When attacking a Harvest Golem with a damaged sylvanas the sylvanas death rattle will proc before the harvest golemn death rattle.

As far as I have read and heard it's the card played first that will have its death rattle trigger first.

When your hero gets to 0 health you lose!

sometimes the game trolls you and when you target an opponents minion with a spell it hits one of your own

"This is my brownie, scrub". "Yeah, reheat it!"
