Ok, firstly, 1.5
> 1
, so by your logic over on clover, this would be mildly OP.
Secondly, I do not think is is fair, nor correct to count effects that cost other elements as 0 for the purpose of this calculation.
I know it is technically true that ice bolt costs 0
, however, that doesn't make it free.
In fact, I would go so far as to say that in any given deck, effects of a non-dominant element are more expensive, because of the difficulty of getting the quanta involved.
To call PU as having a cost of 0
, and thus actually bringing DOWN the average value of this card is just plain silly.
Edit: You also can't assume no excess quanta.
OldTrees, I respect you immensely, but in this instance (arguing that random effect shouldn't lower cost), you are wrong.
