My question to everyone discussing PS here is : Why?
Realistically we are trying to consider if PS is a better stage than Marth's usual counterpicks vs tournament viable characters. The real discussion here is if Marth should take spacies to PS. In that case compare YS vs PS since FD will most likely be the ban due to chain grabs.
Answer: depends on the fox/falco playstyle and the Marth playstyle. If you're afraid of getting camped, go YS. If you want more space to DD camp and chaingrab a bit more then go PS. Both stages have low ceilings and seemingly random stage aspects (the cloud & stage changes) and rather shallow sides also disregarding the size difference.
wait... Why not just go Battlefield where spacies' recovery options are more limited while still having tippable platforms?
just a thought
