Here is a video of when I was starting to get good with the Custom Hydra, I have had some other good games recently, but haven't recorded them since I have been busy. This is obviously ranked, but in general I play similarly in all modes. The only difference is I use more run speeds now, almost 4 mains. You want to play support, but since your ink coverage is worse than other splatlings, use the sprinkler to help, and just lock down areas from afar. It is a really nuanced weapon, and you really need a lot of practice with it, or other splatlings. I am going to write a guide for support, that is going to focus on the splatlings, and how to play them, and the Hydras are the hardest, so I have been practicing, finally winning more than 50% of my ranked matches recently.
Knowing how long you need to charge to reach a certain distance takes knowledge and practice, but is extremely important, I often just go to the practice room to work on these spacings, and time to kill.
The exact gear I run now is:

I do like having the special charge ups, they help with the sprinkler to get my bubble faster, and the ink recovery up is very important, since it helps you with the main weapon and sprinkler. The run speed ups really help you against chargers, and in your face weapons, also rainmaker!
If you have any specific questions, be sure to ask them, but my gameplan is generally as follows:
1. Use sprinkler to cover base, move to center
2. Watch for enemy movements, stop their progression if possible
3. Put down ink as effectively as possible
3. Let Teammates take out enemies who you have stuck, or help team take out enemies, only try to splat enemies who are dangerous to self or close teammates
4. Never die, be the rock of your team, act as a beacon
5. Repeat 2-4 for rest of match, move to 6 if enemies are wiped, or out of way, move to 9 if other team is pushing
6. Push objective, suppress enemies, support teammates by putting down ink on the way
7. Use bubble to save team, and continue push
8. After push go back to 2
9. Fall back, get your team back safely and quickly
10. Use bubble to stop push, keep putting down ink, to maintain some map control
11. After push is stopped go back to 2
Hopefully these will win you games! Also this should be a flow chart, but I have already spent too much time on this.
