Found a couple that aren't listed yet.
Blood Sucker, Rare 3. Goes in the first empty slot on Kurushii's list; you regain a very small amount of life per hit. Costs 10000.
Dead or Alive, Rare 4. Goes in the second empty slot on Kurushii's list, right after Lucky Puncher EX. Not sure exactly what it does; a fixed chance of causing any Counter to become a Fatal Counter, I think? The description is "お互いの攻撃がー定確率で即死攻撃になります。", if anyone's better at translation than I am.
Edit: And a few more. These go right after Free Barrier on Kurushii's list.
Burst Booster, Rare 3. Increases the rate the Burst gauge recharges at. Cost unknown.
Max Overdrive, Rare 4. Overdrive gauge is always maximum length. Costs 30000. DELICIOUS.
Maze Walker, Rare 5. Depth increases much more quickly. Not as useful later on, but early it's a godsend. Cost unknown.
Red Aura goes right after Invisible. Rare 1, +50 Atk. Costs 5000.
Rainbow Aura goes right after Gold Aura. Rare 2, +50 Atk, +50 Def, +100 Heat. Cost unknown.
