Then apparently every single opponent I've played at a tournament misunderstands this concept. Please enlighten me on the exact definition of stage striking, then.
And for the record, it's "C'est la vie".
o.O Typo lol.
Tu parle francais?
Anyways, since you asked:
You are using the random process to choose the first stage in which you just choose random. You make eliminate one stage from the random set only for the first match so that if it comes up on neutral it won't be played the first time. This was from MLG and what you are talking about. This is not stage striking.
Stage Striking(Or, the California Knockout Rule) is where both players take turns striking neutrals until there is only one left. They then play on that stage. You need an odd number of stages for this to work fairly, which is what he ment by: "Good luck stage striking with 4 neutrals". By this process, you can have many neutral stages, and both players will still be playing on one they like.
For example:
Neutrals:
FD
Smashville
PS1
Battlefield
Yoshi's.
My opponet strikes PS1.
I strike Yoshi's.
My opponent strikes Smashville.
I strike Final Destination.
We play our first match on Battlefield.
This eliminates the luck factor of having random on for the first stage.
So there, now you know.
