my point is that your math does not include the reduced flexibility of bringing the flowers, that's why i challenge your math.
It does actually. The negative clause of the mana spent is the reduced flexibility, because every card has this. As zorro was mentioning that if you drop 2 mana crystals you can't summon Adramelech on second turn, however this is also true of any card that you can cast. If you cast 2 of something else that effects the board differently you also don't have any more reduced flexibility than casting mana crystal. So, in the long run what this says is that whether or not you cast mana crystal did not make it so you cant summon that other big card, it's that you spent any mana at all. That is an effect of playing cards not playing mana crystal, thus the only negative inclusion needed is the mana spent on mana crystal.
The table made by zorro is the best representation IMO, because it doesn't omit anything and is perfect in it's simplicity, it just says how much mana has each mage available to invest into altering the game state by any given turn.
The reason his model is not good is because it assumes that the opponent mage doesn't spend any mana. Where in a real game this is, in fact, possible, it mean that the other mage has sacrificed board presence to save his mana for what we can only assume is a really big spell that could possibly equal the board presence of everything the other mage played beforehand. Since the board presence is another variable when comparing two mages we have to equal them out by having both mages play cards that have similar board presence, and the only measure we have of that is mana cost since we see the function of smaller cards having less action potential and more expensive ones having more.
If one mage casts a mana crystal and the other mage doesn't cast anything and moves forward, thus improving his board position (more zones to target, more space to run away etc) and then spends one mana of the saved mana each turn afterwards, thus simulating the channeling +1, both mages will have spend the same amount of mana by turn 6
In the long run what mana crystal REALLY does is allow for one player to play cards with larger potential. Although, as we have mentioned, there is a secondary way to get cards out with larger potential which is saving mana turn by turn. This is where the actual value of mana crystal comes into play because it allows for the +1 channeling each turn to get out a creature or other spell with larger potential than before. Even if both players spend the same amount of mana then the player with mana crystal will still come out on top because he will have either played larger potential cards faster than the other would have, or he will have more mana left over.
Now since were talking about the subtle reductions in flexibility, I want to show you this. It is true that playing mana crystal (as well as any other card) reduces your flexibility, but the original argument was about how quickly mana crystal "pays itself off" before giving you only positive benefits. The original model was after turn 6 but I argued that it pays itself off sooner because of the benefit of having 1 extra mana each turn. So I used a Valuation of the card to functionally express the benefits over time. If you go to this calculator (
https://www.desmos.com/calculator) and input this expression (X-5)+(1*X) which represents my model, you will see the x-intercept of 2.5 which represents how many turns after it is cast to "pay itself off." This even allows for some room for error if you think the benefit of having 1 extra channeling is less than the actual mana gained. If you do think this try putting in .5 where the "1" is and you will see it takes only a little over 3 turns instead of 2.5.
Of course a crystal will give you more options (more mana) in the future, but not during turn 2, 3, 4 or 5. If you value the extra mana provided by 1 crystal during turn 2, you have to value the extra mana of not casting it turn 1, of the potential value of saving that mana from turn 1 to 2.
In my model it does actually benefit you turn 2-5 because you have 12 mana to spend on those turns instead of 10. If you save your mana than you are simply moving the action potential of one turn to the action potential of the next, you aren't adding anything you just end up moving it because you have forgone the potential of a previous turn. So you cannot simply "simulate" the mana crystal as you say. There just happens to be another means of getting those larger cards out. Does that make sense?
But please accept different points of view as not just ignorance,
I'm sorry, I do try my best. Both you and Mortuss have shown care and thought in your arguments against me and I respect that, but I'm sick of it when others just re-iterate what they've said while just ignoring any new evidence that I come up with. That's what true ignorance is.
