That is a fully valid point, which is why I stated that it was only my opinion, I even doubt I am right, but it SEEMS strong to me from what I can tell. I'm not trying to be aggressive or anything, just stating what I think it seems like to me. You are guaranteeing your 1 drop stays on the board and playing other things as well all the while, but maybe it is a fair card since it is merely a cheap and temporary Dreadsteed .  

Yeah but it would spend two lives beating any 3/2, and a 2/3 or 3/3 would trade evenly and this minion lacks any down sides like Flame Imp or Zombie Chow . It could admittedly be silenced but you are still using a silence on a 1 drop. Even a Flame Imp still loses to a 2/1 minion while this is able to do that and still have two lives. The only straight counter at that early stage would be Priest if he was willing to spend his turn hero powering to heal. It is a neat idea, just seems to me like it needs a drawback, then again that is only my opinion.   

Your right that you can't add them up like that, but it still remains that this 1 drop would effectively trade with 1 drops, 2 drops and some 3 drops if given the chance. I am not saying you can just add them up so I likely should have phrased that better, but those stats are still very strong for a 1 drop minion. 

You have some really nice ideas here and I like them a lot. One thing I will say is I think the Darkwood Imp is a bit strong as that is technically a 3/3 for 1. Perhaps in another class I could see that working (but it would still be hard to say), if they really needed a 1 drop but Warlock has some really solid ones already with Flame Imp and Voidwalker so I don't think they need more (they also have Reliquary Seeker if that counts which gives them the highest 1 drop count in the game). One I like A LOT that you made was the Spirit Beast for Hunter. It may not have the most exciting mechanic but it is one I have wanted a bit of in Hunter for a long time as my Control Hunter never fully has the sustain it needs and is forced to settle for double Antique Healbot . Over all a lot of neat ideas, I see a few others that might be mildly over or under powered, but a lot of these are hard to judge in a vacuum. Either way, good work.

Fine, lets compare it to a class card then if you think that is what is needed. Earth Elemental is a 5 mana 7/8 with overload 3, making it technically at a value of 8 mana. Your Frost Wolf has an over all stat value that is 7/8 and only costs 1 more (or 2 less if you count overload) and is distributed in a way that MUST be dealt with by two attacks at least. This is all without also mentioning the beast tag does have at least some value even in shaman.

Some of these are rather neat, though I do have one thing that seems to be an issue. I can't say for the others as they are all somewhat hard to judge without seeing them in play, but the Frost Wolf seems to be a bit over powered to me. Comparing it to a Sludge Belcher it is one more mana and gets 2 more attack as well as a +1/+1 on its deathrattle summon. Another comparison is Sunwalker which is the same cost but a 4/5 and its only advantage to this is a divine shield without the deathrattle. My easiest suggestion would maybe be adding some amount of overload to it, as that is a shaman theme to begin with.

Well aware of how irrelevant my opinion is at this point, but you can barely compare Scarlet Purifier to this card. Scarlet Purifier is far worse than this even with the upped health. It is an anti-deathrattle and with the amount of deathrattle there is, the effect is garbage. You would at most kill one enemy if you were lucky, and even then most things would survive unless they are Haunter Creeper . I am not going to pretend Stable Master is great, but at least it aids a deck YOU made rather than trying (and failing) to counter cards that are either not played, or not weak enough to card about 2 damage.
