I know this weeks lists aren't posted, but
here's a link to last week's Regional results. If you look at the Top 8 decks, all of them are running 3-6 tools each. With the exception of Sableye, none of them play Head Ringer, and most play some sort of tool discarding card.
Puzzle of time is not cutting tools in a decklist. Most likely, you will only use the effect once in a game if you run 4, meaning if you cut essential cards like Float Stone and Spirit Links for Puzzle of Time then something is wrong. It's not wasting space when you adding in tools over tool retrieval cards, which is something you mentioned. If I ran a deck with 4-4-4 Pokeball, Great Ball, and Ultra Ball, I may have 'excellent' Poke-draw power, but it will limit the amount of Pokemon I am running. This is like your example, except you value the addition of more cards that get whatever the card reads as better while it clearly isn't. You can also see that no one is running tool retriever cards from the discard outside of Sableye (who is a literal tool retriever).
I will admit that these are Expanded and not Standard lists and that the format it not XY-BKP, but once the Regional list come out tomorrow you will see the same thing. And even in standard most lists have room for the tech AZ and Parallel City techs.
I also don't know where you got this idea of people being lazy for expanded as well. If you see the decks from this and prior weekends, there was clearly no lack of creativity and ingenuity shown. The winner was a deck that people have never really seen in action with 3-4 Bursting Balloon, AKA another tool. I don't think the decks that won were just 'standard' converted deck, you can see below what they ran:
1. Aaron Tarbell – Trevenant BREAK (XY)/Wobbuffet PHF/Mewtwo EX/Burst Balloon
2. Nathan Brower – Primal Groudon EX/Wobbuffet PHF
3. Phillip Barta – Seismitoad EX/Crobat PHF
4. Mike Canaves – Primal Groudon EX/Wobbuffet PHF
5. Jared Weiss – Virizion EX/Genesect EX
6. Ryan Peterson – M Rayquaza EX
7. Brad Curcio – Yveltal EX/Darkrai EX/Maxie’s
8. Ryan Allred – Eelektrik NVI/Raikou BKT
All of these rely heavily on tools and are not converted standard decks btw.
