I think it is clear and I have it correct in my head, but nobody enjoys illegal decks so I'm going to ask this:
Regarding the usage of races per round/duel/game/match/event/etc... Confirm if the below examples are accurately ruled:
Legal
Round 1
Game 1 - uses zerg, wins
Game 2 - uses Protoss, wins
result 2-0
Round 2
Game 1 - uses Protoss, loses
Game 2 - uses zerg, wins
Game 3 - uses Terran, wins
result 2-1
Round 3
Game 1 - uses zerg, wins
Game 2 - uses Terran, loses
Game 3 - uses Protoss, wins
result 2-1
Illegal
Round 1
Game 1 - uses zerg, wins
Game 2 - uses Protoss, loses
Game 3 - uses Terran, wins
result 2-1, legal
Round 2
Game 1 - uses Terran, wins
Game 2 - uses zerg, loses
Game 3 - uses zerg, wins
result 1-2 due to illegal game 3 deck.
