OK so let me work on the Fish for a moment:
False Wishing Fish:
Seems like a complete waste? You use 1 Quanta and 1 Hp to inflict only 1 poison? Well with 6 in play you inflict 6 posion on the first turn, you lose 6 Hp, on the second turn it is 12 Poison you lose only 6 Hp, 18 Poison for 6 hp and so on... Imagine this with a Puffer Fish Combo...
Wishing Fish:
OK so too costly? Well if I have 2 in play, then I can activate gain 4 hp/4 Quanta, 3 on another wishing fish. As I have Poisedon in play I now have 3 4|5 creatures in play, I have healed and I have gained Quanta that I can use more effiecently.
Just some ideas on how.
So far I think this has been one of the more balanced propisitions I have come up with and thankyou for your advice and support.
Yours
