I think Falcon on Siege is cool.
In the beginning of the match, when the announcer says "Go!" if you do a Falcon Kick, Falcon will hit the opponent across from you, it doesn't matter which platform you start on. Providing they don't shield/spot dodge it. I really only use it against someone I haven't played against, or when i'm really blazed.
The 2nd part is only gay if you fight DDD/Falco/Yoshi. Other than that I like the platforms the statues hold a lot, and the two slanted platforms at the top are good for Raptor Boost wavelands
the last part is meh, it's like a giant Yoshi's Island platform, i think you can RB waveland on some parts of it depending on how tilted it it.
