@ChubbyRain I agree with your post. I just have a remark on the permanent draw engines (e.g. Bob and Sylvan). Does anyone else feel that Sylvan is much stronger than Bob due to how easily a creature dies compared to an enchantment? There are a lot of plows and sudden shocks flying around currently and Bob doesn't stick as easily as Sylvan does. Then again, one could argue that Bob is a great way to fish out the creature hate before mentor hits but, to me, the loss of (future-turns) card advantage is a very significant loss when Bob dies.
Actually, I would find the life-loss from Sylvan Library to be scarier than the fact that I might lose my bob. paying 4-8 life is just not what I want to be doing in a format where decks can put damage on the board so very fast. I am biased, of course, as I am currently playing a deck with 4 Scab-Clan Berserkers in it, but I think decks with 4 Thought-Knot Seer and 4 Reality Smasher can also put a lot of damage on the board rather fast. I'm not saying Library is flat-out bad, but I think it matches up poorly against decks that seek to create damage tempo and put you on a clock fast.
