First up, we have general mono-color payoffs
9 Celes, Rune Knight (Borderless Surge Foil) Offering Incredibly High Potential For Graveyard Revival Although her usability is somewhat more limited than some of Final Fantasy 's other expensive Commanders, Celes, Rune Knight (Borderless Surge Foil) still has plenty to offer for its $185 price tag
You have staples like Cling to Dust, Leyline of the Void, or cards like Bojuka Bog or Crypt Incursion that will also get the job done
Triomes are very powerful lands and I expect Jetmir's Garden, Raffine's Tower, Spara's Headquarters, Xander's Lounge, and Ziatora's Proving Ground to actually be good first picks similar to the tri-lands of Shards of Alara and Khans of Tarkir since fixing your mana is so important
Fear of Isolation Based on Kor Skyfishers pedigree, I suspect this blue creature will see some play
Demonic Tutor alternatives like Diabolic Tutor and Gamble that find your combo pieces for a fraction of the price.
