Sith Accession is worded wrong, it should be "...Sith Lords, Dark Jedi or Sith Masters...".
Thought Bomb should be: "Jedi, Dark Jedi, Sith and Force Sensitive...Dark Jedi or Sith..."]
Zannah (B)'s second ability places damage counters, but speaks of preventing the damage. Damage counters cannot be "prevented". Only damage, before placement of damage counters, can be prevented.
Johun Othone (A) should say "Sith Character cards" and "Jedi Character cards," because the cards are not Characters until they are placed into the arena.
Whiplash should say "...Dark Jedi, Sith,...".
Darth Bane's Flier (A) should say "Play anytime."
Githany (A) needs a starting point and duration added to the Force-activated Crit ability, saying, "Githany gets Critical Hit 2 until this attack ends. Play only when Githany would attack." Or, "Githany gets Critical Hit 2 until end of turn. Play only during the battle phase."
Qordis (A) should require the player to show the cards to their opponent and identify the cards as "facedown", saying: "Reveal any number of Force Sensitive Child cards, Sith Trainee cards and Sith Apprentice cards facedown in your build zone to your opponent and put 1 build counter on each of them. Play only during your build step."
Sith Ritual should say "...Dark Jedi and Sith..."
