Actually, come to think of it. This is kinda just a conditional version of the priests omega card and no one rates that..

Quote from Xetrov >>

Do all omega cards have are all named "omega" first?

 I think so. Sharing the same rarity as well iirc.

I like the card. Being overloaded towards the end of a game and casting Healing Rain with no board always felt lackluster. It also makes spells sitting dead in your hand a little more flexible, especially with Hagatha's random spells in mind.

The effect is obviously good, but the card itself is meh. By turn 10 you have probably used your Volcanos to control the board. You might get to use this with a big AOE every once in a while, but mostly this cards effect comes too late. I quit running Halazeal because turn 10(the turn you can play him with Volcano) was normally too late to get good value out him

This is going to buy more time to find Shudderwock

I'll use him in my Overload Spellstone deck

.....it sucks though because i feel Combo decks are going to suck all creativity out of the meta for the next couple months

I know that Wock Shamans need better control cards so they can survive long enough for their combo, and I'm not sure if this card fits the bill. It won't help much against aggro decks, since I'll probably only have time to use its stats and not its battlecry, but this card would be worth considering in most other matchups. This card would pair well with Volcano, for a massive swing in tempo.

Good effect

It's so obviously bad I don't even understand why people are all over this card. When do you need healing? When aggro pressures you to get out of kill range or when some is setting up a 2 turn KO. In the first case it's useless because you won't survive to turn 10 and a river croc isn't gonna do much in the early game. In the second case it can be useful but there is a chance your damaging spells won't have anything to hit so you can lifesteal. Even if they do, the omega dude takes 3 damage off of your volcano (which is the best board clear and highest damage spell). It's good with lightning storm but I don't see a meta where you need both this and healing rain. 

tl, dr: Healing rain is more flexible and reliable. Don't have room for 4 healing card slots. 

This is basically a worse version of Hallazeal the Ascended, a card which saw almost no daylight. As stated above, on turns 10+ it's likely that the Shaman already used up their AoE just to survive (since e.g. Lightning Storm is unreliable as a board clear) and Control or any sort of Combo deck couldn't care less about such a conditional heal. So, as long as Healing Rain is available this card will suffer the same fate as the legendary.

This was my first thought. Shudderwock/any deck that can carry this get really good. Since even Even Shaman can get some interesting spells with Hagatha.
