Workaround for Trophy Pushing (Sniping THs)
After the MM update, it seems like matches are found in descending order (based on trophy amount) with occasional dips upward. The more you next in a single session (without going back to village), the weaker your targets will get. This both beneficial and harmful depending on your goal. If you're looting, it's great because those weaker targets often have a lot of easy loot to collect. If you're trophy pushing, it would be devastating because after a while, all you find will be 1-trophy targets! The algorithm is unchanged for 3200+ cups (cups NOT league, if you drop below 3.2k while you're still a champion, the new algorithm will still apply!).
The solution is very simple if you want to trophy push: Return to village after nexting 2-3 times and initiate a new search. That will reset your match queue in descending order again and your first few targets can be potentially sniped for high amounts of trophies.
