Weird/New tricks to learn?

Watch videos from the 80's and 90's, and that will give you some ideas of less common stuff.

Candy bars , nothing's , rocket airs

Watch Ian Schwartz, Steve Hamilton, garrett reeves, Cameron wood, garrett Byrnes. I like doing weird stuff and they're my biggest influences.
Finding new lines is always fun too, even if they're not big, just trying to use things in a way different from their purpose opens up a lot of possibilities and ideas

Learn superman decades over jumps , probably the most badass trick you could learn

X-up ride variations

Watch Matt Beringer, Erik Elstran, Mathias Dandois, and really anyone out there that isn't just riding foot tall ledges and banks.

See how many different things you can slide your tires on. Pretend you skiing or surfing or snowboarding and slide everything. Do 180s and slider the rest of the 180. I also just learned flat ground 360 ETs yesterday. Those are super fun.

Use brakes. That's rare enough these days. Front brakes specifically.

ET's, crank flips, heel clickers, peg manuals, fufanu, abubaca, wheelies, rock walk, peg chinks, and luc-e grinds to name a few! Some good ol bmx tricks!

hop rocket manuals, rocket manuals off ledges or boxes, rocket grinds, rail rides to 180, 360, jailbreak, halfcab tbog

Nose the top of a ledge and then drop off the side and lockout tooth chink it

60/40 a ledge

Learn back pedal grinds or butchers

Rollout into an x-ride. Basically rollout and keep your wheel turned the same way the whole time.
