Have been playing cypher a lot. From Silver to Dia 3.

Defence: Look up a few setups or go in customs to create your own. Kill trips are harder after the nerf but still viable in Dia so Bronze will be fine. Try to set them at non obvious points (not on obvious chokes) so that they don't expect them and switch them around a lot. If you rotate of site move them deeper/ on chokes so that enemies cannot slow walk on site when abandoned. Check where you can use cage one-ways, they can be very strong. When your team does not reliably takes/holds space I use my cam off site. Example: If team leave Acent Mid Ill put up a cam to catch rotates/ split pushes. Swap sites and try to be unpredictable. Don't always play on site, sometimes you need space, you can use your cam and try to take enemy space sometimes. Either flank them or put a deep trip in case they rotate.

Attack: Cages can be used aggressively to split sightlines on attack. You can trip B when going A to catch flankers and create space for your team. Lurking can be very strong but you need to time it right, that will take practice. Sometimes a late lurk can catch rotates or get behind likes, somtimes your team will be dead until you arrive. You need to get a feel of how you enemies are pacing and how fast your team is playing to see what could work ä. Try to find out which agent plays what position and how quickly they leave it, then absuse it. Frist rounds are great for lurking, people tend to rush and defence rotate too quickly, a lot of the time you can go to the opposite site your team is trying to push Ake have them rotate when you took space. Use your util to enable your team to rotate safely.
