In this meta, it's a dead card. I will explain this in depth. First of all, it's a 5 mana 8/8, but you won't be able to use this on turn 5. In order to do this, you need to play 7 Deathrattle minions. On mulligan, you always get this on turn 1, so you are actually playing with 2 cards (if first). These 2 cards need to be Deathrattle. If you have perfect mulligan and draws, you can get the legendary on turn 7ish. Now, the effect. Set your Hero's Health to 40 can actually mean 2 things. 1st and most likely scenario is that your maximum HP will increase from 30 to 40. It won't actually get you this instant to 40HP. The second scenario is that your Health will be set to 40 as maximum and then you will be healed (but since it should be on the card, it's not likely). Overall, if we don't get Sludge Belcher-level Deathrattles, this shouldn't be a great card. In my opinion, it's a 6/10 in usefulness if you get a PERFECT mulligan and draws.
