Everyone keeps mentioning how they don't like doing math, so I made something for you. Attached to this post you'll find an excel sheet that will calculate the power for you. It seems a little unbelievable that anyone could dislike math. After all...
Do you know what my favorite thing about Deckstats is? The stats.
Power levels of my decksCurrent decks are in bold. All the others are retired decks. I've ordered them by what I think is strongest to weakest.
Captain Sisay: 9.70
Edric, Spymaster of Trest: 11.75
Krenko, Mob Boss: 9.77
Atla Palani, Nest Tender: 12.69
Ruric Thar, the Unbowed: 11.57
Narset, Enlightened Master: 7.23
The Scarab God: 10.13
Haldan, Avid Arcanist + Pako, Arcane Retriever: 9.15
Kynaios and Tiro of Meletis: 11.50
Ezuri, Claw of Progress: 8.67
Brudiclad, Telchor Engineer: 7.86
Mishra, Artificer Prodigy: 11.87
Vaevictis Asmadi, the Dire: 6.43
So... yeah. I don't think this formula is much good as it stands. The high value on tutors makes sense for proactive decks, but any sort of interaction is hugely undervalued. I like that this is a legitimate attempt to quantify deck strength, but it needs a lot of work.
The infinitely many parameters trapSo everyone is already pointing out a lot of the glaring flaws with this formula. Some cards like
Demonic Tutor and
Diabolic Tutor are weighted as the same. It seems to over-value tutors and undervalue interaction. Let's remember that like most models, this is based on arbitrary values. I don't know why twenty, out of all numbers, was used to lower the relevance of interaction, but whatever. It's nice to see this as a starting point. And sure, we can try to make changes to get a more accurate rating, but then you run into a problem called the infinitely many parameters trap. Let's use an example:
I also think the removal portion could be separated into more variables, lending different weight to stax effects, targeted removal, and board wipes. I would even go as far as to say that certain kinds of board wipes should be given higher value than others (symmetrical v asymmetrical, types of permanent hit, destroy/exile/bounce).
First we need to add weights to give different values to stax, counterspells, targeted removal, and boardwipes. Then we need to weigh wipes that
exile, destroy, and bounce differently. Then we need to differentiate between wipes that are one-sided, ones that leave commanders, ones that let you select targets, ones that give -X/-X, ones that
deal damage...
Infinitely. Many. Parameters. You can literally go on forever with adding variables and weights. Unfortunately, there has yet to be a consensus on the best way to stop the infinitely many parameters trap. It's a huge debate in stuff like phylogenetics where you can measure things in different ways
ad nauseam. There are some models that are able to stop the trap, but they are beyond my understanding (these models also don't work in every situation). Instead, most people decide that at some point, what you're measuring is mostly irrelevant. I don't know what that point is for this model. Should the difference between an
exile and a destroy boardwipe be relevant for this formula? I have no idea.
