What Pokémon card makes you unreasonably angry?

It doesn’t matter the conditions, as soon as someone puts a Darkrai EX into their bench I get pissed off and want to quit the match. Like there’s just no reason you should be able to do 20 damage for just existing. I DESPISE it.

So, I’m just curious what other pokemon line up pisses yall off? What pokemon do you see in someone’s deck then get pissed off?
