Extended U/G Madness deck

U/G Madness use cards with the madness ability in order to play them for less. Popular cards to use are basking rootwalla and arrogant wurm along with wild mongrel, the key card to the deck as it fuels discard for madness and it gets bigger and bigger. They also wonder to give all their creatures flying and then beatdown on you. For the blue section, they use card draw that also makes you discard (careful study) and deck search that puts things into your grave (intuition). Roar of the wurm is also used because of it's ferocity coupled with wonder and circular logic for control purposes (you should have a big grave and they shouldn't have enough mana to pay for it).
