Substitution Plan
By strategically subbing, we can have fewer matchups next round. Our vault will be slightly smaller, but it will be worth it because we will have fewer matchups.
How many wins and losses do we have?
0-0, 0-1, 0-2, 0-3
Do not substitute.
1-0, 1-1, 1-2
Have a player substitute your match.
2-0, 2-1
Do not substitute.
3-0
Have a player substitute your match.
I think this is right, but someone should check.
EDIT: Small fix, I think.
