Delirium Skeins

This card is awesome: in a madness-based deck you want to discard your hand, and unless you're playing against a similar deck, your opponent isn't going to be too happy when he has to pitch 3 cards. It's also good with Hellbent, and with cards with Retrace, and with Mortal Combat, and with Megrim, AND with cards like Makeshift Mannequin. This card in a casual deck could be the bomb!

Probably the best card for the Hellbent mechanic, as it allows you to get rid of essentially four cards in your hand, and then take three of your opponents as well. If you manage to incorporate some madness as well, it can be devestating

If you can back the card loss up then the card is fantastic. No need to have both offensive or inferring discard cards, i.e. discard your own hand for various strategies, when you can play this. And the number 3 makes things worse... both on the mana and discard front. The problem is the card itself takes up a card slot, meaning your hand will likely be emptied if the draw comes up without deviation from the common. But, if it can be made up for, well... it's great. Haven't seen a common this powerful in type 2 block, but I only check black ;)
