Final Destination is difficult to play on because of Robin's speed, the length of the stage, difficulty recovering, and the distant kill zones which put more emphasis on edge-play than the quick, low-percent kills Robin excels at. To play on this stage effectively, a number of skills are helpful; such as the ability to land an Elwind spike and a Nair gimp, to tech stagespikes, to be frugal with the easily-punished Arcfire, to charge Thoron on a flat plane with nothing to defend you (namely, the ability to judge the maximum travel distance of projectiles and shield/dodge in time to avoid attacks when charging), to mix-up recovery, both horizontally off-stage and on return from ledge, and so forth. I'd say you could categorize skill into 5(?) or so types:
1. General Smash Skill
2. Specific Smash Skill
3. Character Skill
4. Anti-Character Skill
5. Stage Skill
I'm sure you could say there are others. But like the other guys said, the FD map will give you a disadvantage that can be made up for in the other four types of skill as well as a specific stage strategy and well-honed skills to utilize it.
