Hearthpwn

Definitely not useless. 

It's a bit finnicky. Great if you use it fully up to round ~2 (fully=it has cards to buff already). Late game it appears closer to a waste of mana unless you really want to kill something with 0 attack you have on board yourself and have no other way.

Priest has the 2 mana 2/3 that gave another random minion +1/+1, which saw fringe play. 

Now granted, buffs like this are better in shaman, and the scaling an additional minion (that you can also “target) is a bit better. 

Idk though, a cheaper albeit delayed fungalmancer today? Who knows.

I think its fine buffing 2 minions per turn and 3 health makes it a good target for alot of spells/target things in the game if it had 4 health it would be bad but that effect for 2 mana is alright. Compare it to for example Flametongue, I would argue that Flametongue is better in more situations than this is and its not a card thats a problem. It could trigger a comeback of a totem focused Shaman though thats something.

I kinda like this card even if I hate the old Totem decks Shamans had but I do think this fits Shaman nicely and it doesnt feel broken or anything.

That's hella strong. Maybe is so pushed to remind our fellas gamers that hydration is very important.

As a Wild player, I kinda hate it. Like, make it cost 3 just to avoid it being able to slot into Even decks.

"What wild?" ( Devs, probably)

I am not really sure what other totem card you would swap out for this one though

To be fair, Even Shaman is currently punted to the bottom of the list by even more hyper-aggro nonsense in Pirate Rogue / DH, Shadow Priest (Aggro and Control), and others. Looking at the current list, honestly it could replace Flametongue Totem in some situations. Either that or Jam Session or Crackle.
