Countermagic : Mystic Snake, Frilled Mystic, Draining Whelk Reanimation : Karmic Guide, Phyrexian Delver, Extraction Specialist Milling : Manic Scribe, Thieves' Guild Enforcer, Sage's Row Denizen Self-Milling : Stitcher's Supplier, Satyr Wayfinder, Balustrade Spy Discard : Burglar Rat, Mesmeric Fiend, Sin Collector Goading : Insufferable Balladeer, Jeering Homunculus, Vengeful Ancestor "Gain Control" effects : Hostage Taker, Agent of Treachery, Gonti, Lord of Luxury Clones : virtually all of them, though a few are decently pricey
