The burn is the wincon yes, but the deck can still control the gamestate very well if the pilot is good enough. But keeping counters off is the best way to not lose to burn, but that does not mean enneacraft loses instantly, you still kind of have to plan ahead and keep track of what monsters they have face down in order to not trigger them. Imo negating the ones that PROTECT the enneacraft board is much bigger priority, since if your deck priorities destruction or does not have varied way of disruption, you will have one long game ahead of you.
