Well I've got everything available which you listed apart from Darkrai available - So depending on how you value Terrakion and the cards I'm offering I would do :
My:
- Hydregion (Good)
- Blend (Psychic Dark)
- 2 Random Reciver
- 4 Max Potion
- 8 Dark Energy
Your:
- Terrakion EX FA
LMK how you feel about that and feel free to counter
Donez
EDIT - Sorry I've only got the 2 Max Potion available now
Still, let me know how you view the original offer and if you're interested I will add another something in? Thank you
