Reprieve - The problem with cards that return to hand rather than counter, like Unsubstantiate, is that you run the risk of them just being able to recast it right away if they have a lot of mana open
Note that the damage doesnt even have to come from sources you control, so things can get out of hand fast
This, ultimately, is why Yawgmoths Bargain was banned in 2006
It has included crossovers with properties like Lord of the Rings , Transformers , and Warhammer 40,000
Even a deck like Lantern Control with a highly unique angle of attack depends on seeing what card the opponent is about to draw so they can decide which ones to mill
The deck is also filled with items and Characters that can remove damages making this strategy more efficient and you can try to look for the cards you need the most by having Aurelian Gyrosensor in play to go pick the first card of your deck every time you quest
