Those are good suggestions. I don't own Sargeras yet, but I may craft him. Gnomelia and Jaraxxus are great. I'm not claiming I have endless answers to all threats combined, but the Ox can be dealt with using Reno, and Mind Tech Controller has a word or two about big boards. Gift of Gul'Dan can discover a Twisting Nether, too. There's not much against weapons, but the deck is not defenseless. Asides from a Viper in ETC's band, there are some taunts available too. But I'm fond of the miniaturize minion that generates frost spells, that can sometimes put a kink on the weapon-wielder enemies. I'll probably update the deck and show more gameplay soon. Thanks for the comment.

The main consideration is that eventually I want to play Rafaam and turn the cards into legendaries. "Random legendaries are always good" , I've heard. There is a significant chance I can grab legendaries with the no-duplicates rule during the course of the game, hence the wide variety of cards. I also like the challenge of playing with less popular cards, which in a way adds the element of surprise to the deck's strategy.
