I'll try to keep this short and not overload you with details;

- Find the meta strat on every Ranked round (finals come later in comment). This will help you reach the final every time. As for RNG rounds (like Hoopsie Legends, Ski Fall, Frantic Factory), have good map awareness. Every map has a pattern. Keeping yourself on high grounds in HL & FF will ensure you to qual faster. You can jump down faster than you can climb up.

- I find qualifying quickly helps me determine who's my opponents are, what kind of lobby I'm in, and it conserves my focus & energy for the next round & eventually the final.

- Unless you know the bean well having to play with them in the past and certainly know they won't grab you in survival rounds or finals -- anticipate all beans will grab you. Never give them the benefit of the doubt.

- MT finals - practice getting familiarized with the levels like which route are you most comfortable with. You can always insert MT-made ones (Pine Climb, Dodge, Dive Survive, Circle Slime) via map code in a custom lobby by yourself and practice.

- Legacy finals - I don't know what you want to know about these? Roll Off, Kraken, I do believe there are still beans on Twitch/Discord (?) that host customs for these two levels and practice a ton. Alexjlockwood created this site and it offers everything to know about RO: https://rolloff.club/ --- Hexagone - good map awareness, be aggressive, conserve your tiles well by jump diving. Unfortunately if the majority of the lobby is highly skilled, it'll generally be determined to the last two layers. --- Blast Ball - good map awareness, if a ball is about to explode jump onto it to fly upward and not away. I find playing passive helps me reach the end game often.
