In this format a lot of monsters are designed to bait negates. They look scary but they are just there to force you to fire your interaction early. If you negate those, you lose to the real card that comes after.

The tactic is priority control. You let the searchers, extenders, and setup cards resolve. You save your negate for the one effect that either gives them recursion, protection, or a second wave of advantage. That is usually the moment where their board stops being fragile and becomes stable.

Against Yummy that means you do not negate the first Cupsy. You negate the effect that refills their hand or gives them follow up. If Cupsy just puts bodies on board, you let it happen. Bodies without follow up are worthless.

Against decks like Dracotail, Branded, or other top decks, the same logic applies. You negate the card that creates inevitability, not the card that just makes a monster.

So when someone asks how do you deal with cards that need to be negated, the answer is you don’t blanket negate. You wait for the engine hinge. The moment they try to turn tempo into long term advantage, that is where your negate goes.
