Hey, It was about most poison, there is never said I couldn't use the trainer.
Also, I don't have that many upgraded cards as you 2 have, but yes, I think you could inprove it:
What if terro used arsenics + purple nymph + green nymph,
They would heal you, they would do 2 poison a turn, and the green nymph could be used on your staffs too.
I used deja vu + fractal to fill my field, which works extremely well, because you only need 1 fractal, and after that, they have no ability, so you can use luciferin to power the miracles.
*goes to think about 2 good combining decks*
