But lets say pokemon A is faster than B.
Turn 1 - A uses disable and disables seismic toss and B attempts to seismic toss but it fails.
Turn 2 - B switches, A uses an attack that does damage (because disable reset the damage counter)
Turn 3 - B switches again, A uses Counter
This would be an interesting test case. I suspect that this could cause a desync, but I'm really not sure.

Disable will reset the last damage done, so counter will fail.
In RBY disable chooses a random move.
Whirlwind doesnt make you go second in RBY, but counter will.
The old understanding was that if both players Counter, Counter fails. But that was possibly due to a poor test and in fact it may desync.
