I like this a lot but I don't know what deck wants it.

What a splashy card!
A cool niche ability with a weird setup cost but it doubles as surgical grave hate?
For EDH play I don't think I personally see enough activated abilities but that's the only threshold that needs crossing for me.
Obligatory "4mv blue instant with Set Mechanic that looks at the top N cards of your library and puts 2 into your hand"
I do love to see it, though.
This seems really fun even though I can't tell if it's good. In EDH I can see Grixis theft decks slotting it right in because it draws, ramps, and even steals!
You can have one legal Otter in EDH, as a treat.
This might be enough to make me build UB flash.
In Commander I can't decide if it's a Goad build with a side of Flash or the other way around.
Good to see them all (?) in one place!

The model certainly has some obvious flaws like you noticed with Dynamo and Powerstone. I don't think it "counts" words or symbols on cards and it definitely doesn't have a notion of the "role" a card might play in a deck other than its key words.
I like using it when I have a card that has a niche intersection of mechanics/words and I want to find all the cards that are as similar as possible without manually searching every possible subset of those mechanics or words.
That's exactly correct. The similarity model basically ranks the importance of keywords based on how rare they are in the entire body of text. So for Counterspell "target" is pretty much irrelevant because so many things target but "counter" and "spell" are significant because they're rarer. Then it more or less quantifies the similarity of any two cards by how frequently they use these important keywords.
I see they're continuing the "1mv black instant removal meme card cycle" from [[You are Already Dead]].
