Oh, that's what spoilers do? I already forgot.

Hello. You should be familiar with graphs, mostly, and methods of search in the graph.

Fixed last issue in kata, would really appreciate more feedback to get it out of Beta: https://www.codewars.com/kata/5d4bed7c7a528071756060d8

Clarified it in the description.

Hello! Made a new kata, please try it and leave feedback.

Only problem I can think of is generation/testing time. But with new solver I definitely can generate more fancy test cases.

Good point, okay, I'll implement playback validation.

This kata is "step one", I have at least another one planned (maybe more), with more difficult conditions.

By "same resource" I mean all + are indistinguishable now and it really doesn't matter which one is spent on card activation.

I have two random tests now. Generating these on the fly is kind of hard because you may accidentally create unforeseen combos.

But, I'm open to suggestions.

Also same resources are indistinguishable from each other (at step 1, at least).

Alternative solutions should be okay now (no card-by-card executing yet, but still).

Good point.

Been thinking about a puzzle like this for several days. This is the simplest form, there also will be more difficult ones. The idea came from the question: "If we have a database of Magic: the Gathering cards in format useful for reasoning, will we be able to look for combos automatically, and if so, how?".
