I don't see the Dragon Kite; only Flying with Mechanical and only "doublecounter" to beasts..?
Anyway, fun list!

But not all pets you face have attacks of the same type as what they are.. It looks like your site is built on a database, would it be easy to add an option at the top to enter a type of pet with types of attacks, and have a little script to find the "doublecounters" for that combination? Would be pretty awesome
Not sure if you had seen this post of mine before.. I had made a table that shows all combinations of families and attack types, and what would be good against each, but it's hard to use as the table is way too big :/
Maybe you can do something more practical that would serve the same purpose?
