I agree completely. As long as blizzard makes the disenchant exchange rate 1/4th, people will be punished for buying older expansions. This makes it much harder for newer players to come in, because they won't want to buy old expansions for meta cards.

Zoo has a surprising amount of cards with 3+ health, making it a bad idea to ditch auchenai+circle. If zoo is actually giving you trouble with this deck, I would recommend getting rid of something like entomb(only one) or barnes. That being said, zoo should be a decent match-up anyways, so I am not sure if you need to worry about countering it with tech choices. If you are having problems with zoo it probably comes down to not understanding the zoo match-up, instead of the deck.

I'm not going to speak for him, but I will try to help. Replacing Loatheb directly is quite hard, due to the uniqueness of the card, so it's hard to "replace" it. That being said you can add things based on what you are facing, here are some examples... if you are running into a lot of face/aggro decks you might need to stack up more board clear, such as Holy Nova, Wild Pyromancer, and Eviscerate Evil. A good tempo option is Injured Blademaster, which makes your deck a little more sustainable vs minion spamming decks like zoolock, another good tempo option is Sylvanas, for a lot of the same reasons. Against control, perhaps another thoughtsteal or mind control.

EDIT: Another good option vs fast decks is Mind Control Tech

I wouldn't recommend Rafaam. The issue is that grom is very hard to replace directly, but there are plenty of cards that fit into patron well. You could add another frothing, another unstable, cruel taskmaster, loatheb, and some others as well. 

What a nice guy :)

whoosh

I don't think it's that he is good but that there weren't really any annoyingly broken cards in TGT that make everything else seem weak in comparison. Perhaps Mysterious Challenger, and new pally secrets in general, but other than that there was nothing like undertaker/boom/thaurisan/patron. So he most certainly holds up with the rest of the cards in TGT.

You know, it could always be that you're not good with the deck.
