Bizarre deck based on a mix of synergies between Wailing Soul and Youthful Brewmaster/Ancient Brewmaster and, to a more limited degree, Recombobulator. Essentially, this means that cards need to have impact generated by their casting, but that isn't removed by being silenced. In other words, they need to have Battlecry or Choose One effects.
Darnassus Aspirant benefits from being bounced, silenced, or recombobulated, and was the 'core' card of the deck. Ancient Watcher was the next obvious inclusion once Wailing Spirit was going in. Antique Healbot makes for a great bounce or a great Recombobulate, as does Ancient of Lore -- and neither are penalized by silence, so bonus. Nefarian makes for a solid late-game plan backed up with a Youthful Brewmaster to turn him into a card engine, or a Recombobulator to turn him into...well, any other 9-mana minion after he's soaked up an enemy minion or two.
