The easiest way to beat our deck is with graveyard hate like Rest in Peace or Leyline of the Void

Plays well with: Teleportation Circle, Maskwood Nexus, Eerie Interlude, Mentor of the Meek, Anointed Procession, Divine Visitation, Mirror Entity, Panharmonicon
All of this should help you maintain a strong board presence, whilst continuing to tick your Planeswalkers loyalty up into ultimate range
Not outright evil, then, but definitely not Heroes
