Spy Combo wants to flip Balustrade Spy and chain Dread Return's flashback (sacrificing three creatures) to reanimate a huge threat, both of which are graveyard-dependent, so Faerie Macabre's discard-to-exile ability is excellent at removing the Balustrade Spy triggers' milled cards or key reanimation targets before they can be brought back. The second Ram Through gives you another way to use a big hexproof creature (especially one carrying Armadillo Cloak or Rancor) to kill their ramp creatures like Overgrown Battlement or Wall of Roots, slowing their mana engine. Keep your aura suite intact since their deck has no removal that targets through hexproof.
