And this is where the pro mana flower logic breaks down for me: If I save the mana, instead of spending it on a Flower, the next turn I have far more options available than even +1 channeling would give me. It seems like we've been ignoring the opportunity cost of the mana.
Please watch the video I posted to better understand my points. I know you're new to the conversation but you are regurgitating information that has been said and I have reacted to in detail.
https://www.youtube.com/watch?v=oqMV0wBFu54You have created a model to give you the "value" of a card. The problem is that it is not possible to assign a value to a card, due to the complexity of the resources in the game, and therefore this analysis does not tell us anything useful.
This is incorrect. You can assign a value to anything and, in concept, it's actually pretty easy. By analyzing traits and giving each certain effect value by ratio you can create an index number to represent a card. My analysis does not include every single trait that the mana crystal holds but rather the most important ones. This does not give the most accurate index number but it's good enough for the relationships we are trying to draw between cards, because the only application of the index numbers we can create is only relevant in comparison to each other. To say that it is impossible to create index values of a card is to say that you cannot compare goblin grunt to adramelach and definitively determine which is more useful. You are correct in saying that there are a ton of elements to consider when doing this but just because the solution isn't simple, doesn't mean it's impossible. I also find it curious that you deny the existence of such a process then immediately attempt to due one with your meditation amulet example. (Which is interesting by the way, I like it. So much that I may include it by concept in my own valuation to make it more accurate. However I'm not sure I totally agree with your valuation of a quick action. Actions are often in flux because one possible and often feasible action is to do no action at all. But I digress.)
Now to answer the action potential question. Action potential IS measurable, it is what a card has the ability to do, more or less. Now this is a complex concept as it is "potential" meaning it has not done what it has the ability to do. Mana crystal, rather than increasing it's own action potential, increases your mage's action potential, and that is where I'm getting the .5 by physical account. It increases the amount of stuff the mage can do on a per turn basis. The fact that .5 is the number .5 is because I believe that, by ratio, the increase in action potential is worth half of that of each mana it gives you back. So basically, the card's index value increases by 1.5 each turn after it is cast until the end of the game which is the only point in time which you can fully and accurately asses the index value of the card. That is why we must use variables in it's value assessment equation.
So perhaps you are correct in saying my valuation is not complete objective, but it's also not objective from the stand point of each mage as well. Especially until we include a clause concerning spell points and those heavy on zone-exclusives.
So in conclusion, no, my valuation is not simple and is far from totally complete, but that doesn't mean that it is irrelevant. Isn't that what progress is anyway? Finding something that works until we prove it wrong and then we refine it further so it works again.
