Yes you are right it would lean towards OP if that was the case. The original idea was that it copied the spell and then you could use it with
this did not mean you could use the relative ability of it unless the card specifically said you could. (ie a card that said use the same quanta as you paid for this card)
So with Fire Bolt you would use 3
(Taniwha) to activate it but you would still suffer the idignity of needing
to use the ability. This would hold true for StoneSkin and Drain Life. as well. The only exception is Miracle as this would definately be OP if you could cast it with
and not have to lose anything for the casting.
As another note would someone be able to clarify if Unstable Gas is a spell when you activate the
cost of it thus making that available or not? I would assume it is not although being able to summon an Unstable Gas would be available just not the ability activation.
