First Match
1. Do I want to get some practice in with or otherwise have a strong desire to play a specific character? If not, skip to 2. If so, select that character and play.
2. Is there any possibility of this person selecting a character that creates heavily one-sided, tedious, or otherwise unwanted matchup for my main? If not, skip to 4. If so, skip to 3.
3. Do I feel like dealing with this matchup at this moment? If not, play a secondary that is better equipped for the matchup. If so, skip to 4.
4. Play my main.
Second Match
1. How did I do in the previous match? If I clearly dominated the match (two/three stocked with a low percentage left, had the lead at almost all times, was almost never in a disadvantage state, etc.), skip to 2. If the match was fairly close and I won or lost by a small amount, skip to 3. If I clearly got destroyed in the match (was two/three stocked with a low percentage left, almost never had the lead, was in a disadvantage state at almost all times), skip to 3.
2. What were my observations of the opponent? If they seemed to be much worse than myself or did not seem to take the game seriously, play a character other than my main and see how I do. If they seemed to be skillful, but simply had a bad match or were unfamiliar against my main, skip to 3.
3. Do I want to get some practice in with or otherwise have a strong urge to play a specific character? If not, play my main. If so, select that character and play.
Third Match and Onward

If I clearly got destroyed in the match (was two/three stocked with a low percentage left, almost never had the lead, was in a disadvantage state at almost all times), skip to 4.
2. What were my observations of the opponent? If they seemed to be much worse than myself, play a character other than my main that I want to practice with. If they seem to heavily struggle with fighting my main, play my main.
3. Do I feel as if I have used my main too much, or that my opponent might be bored of fighting the same character? If so, play a secondary. If not, play my main.
4. Play my main.
