Attempt at legitimizing a Hellcarver Demondeck.

Combo goes like this- bring out Hellcarver Demonand protect him with counterspells.

Once you have him ready to swing use Insidious Dreams to put Faith's Reward and as many big monsters as possible on top of your deck.

If you have too many copies of cards you need to cast with the Hellcarver effect you may use Library of Leng to put them back into the deck before tutoring them to the top. Since you can always discard them for Insidious Dreams they are never dead cards.

Proceed to not get screwed over by Hellcarver's absurdly huge downside as you retain all the sacced permanents and tutor with the cards you would have discarded.
