This would be a lot better if it was explicit that the testcase was looking for all lower-case "modifiedstrength" rather than mixed case "modifiedStrength" as stated in the prompt.

Fun theme and idea behind this kata, but description could be improved. As others have noted, it sounds like wins and losses are going to be marked by either a 1 or 0 when in fact we see other values.

Also I think that this kata should be a 6 kyu. It's as difficult, if not more difficult, than this one which I completed recently https://www.codewars.com/kata/580d08b5c049aef8f900007c

Why just doesnt explicit says that you have to add or 'SUM' the records instead of struggling us with the stuff of 0 & 1

It's a nice kata but not clearly defined instructions

Not really cryptic. Binary, perhaps.

Instructions Unclear

Am I wrong in thinking this kata discourages proper null handling by making tests fail that include it?

It seems difficult at first, but when you start to code it's easy and very funny!

Thanks! Yeah I like the fun stories too. It made it more fun to write, anyway.

Thanks! I'll take a look and try get this fixed, been a bit of a while since I used the interface.

There is a bit of inconsistency in the namestilles in this kata:
CamelCase & underscore (pokemon_name & modifiedStrength).

But anyway, thank you! I enjoy your katas)

Truly immaculate kata, thanks a lot!

I really like this kind of kata, I practice my SQL skills while I'm having fun with original descriptions

Next time give UML
