Sylvan Library provides exceptional card filter and can produce overwhelming card advantage completely on command.

Dark Confidant has a relevant set of legs and produces a continuous stream card advantage for every turn that he's allowed to live.

Jace is a Merfolk Looter that flips into a dumpy planeswalker that can be completely ignored.
