my other gym would be a ghost gym. the 8th gym.
my team:
![:Gengar:](./images/smilies/Gengar.gif)
Lv. 47 Hypnosis, nightmare, dream eater, toxic
![:Dusknoir:](./images/smilies/Dusknoir.gif)
Lv. 49 Calm Mind, toxic, gravity, earthquake
![:Froslass:](./images/smilies/Froslass.gif)
Lv. 48 ice shard, hail, ominous wind, confuse ray
![:Mismagius:](./images/smilies/Mismagius.gif)
Lv.50 power gem, mean look, perish song, lucky chant
![:Banette:](./images/smilies/Banette.gif)
Lv. 47 embargo, shadow ball, shadow claw, dark pulse
the puzzle would be a maze with trainers lurking at every turn, where beating them makes the light brighter. (like bradley's gym only much bigger)
