Best PVP tricks to practice?

What are the most important in Minecraft Pvp (Skywars) and how can you practice them?

Most important of course just practice Pvp at e.g. Duels

then Bridgen and water mlg, plus there's a training server

I think that combos and rod-pvp are the most important things you should be able to do or be able to practice.

There are servers like Skywars.world where you can practice this.

First of all, I would practice PVP and your reaction speed and that you can build very quickly, e.g. To save yourself from falling down.

I think that would be it too…

(But practice makes perfect XD)

I have to say: I can FastBridgen, Butterfly (up to 12 cps), but I miss the hotkeying… So this tactic, the quick change between items etc…
