Well, he's right you know. You should try to read the card effects for once. It's stated that "at the end of the Damage Step, if this face-up Attack Position card battles with an opponent's monster: Inflict damage equal to that monster's ATK to your opponent, also destroy that monster." It works both ways, whether your monster attacked the yubel or the yubel attacked your monster.
Finally, someone who understand. Might need a sticky note to write that and stick it up his 🔥 so that he can remember that for the rest of his miserable life. REMEMBER THAT MAH BOI THE STUPID IDIOT WHO NEVER READ THE CARDS EFFECTS.
you should read a book titled "how to punch someone through the internet". I'm reading one right now. Some people really dont deserve to have access to internet.
I'm guessing that you forgot to read Yubel - The Ultimate Nightmare's effect. Its effect allows it to inflict damage equal to the targets ATK and destroy that monster plus not receive any battle damage. Vapor will not be destroyed by such an effect but you will still receive the damage of Vapor's ATK. If I were to use Vapor deck then I'd place the one that negates DARK effects in there.
Well, that's unfortunate. I thought Vapor would block the effect damage the same way Stardust Dragon does. I guess Stardust negates all effects if just one of them destroys a card (which doesn't happen with Vapor). Maybe he's a better option to farm Yubel...
You need to get that stick that shoved way up your 🔥 because you're not a tough guy just a 🔥 who acts like they can come off like smartass and it's okay. NOBODY likes a smartass and that's you so perhaps you should get your 🔥 straight before someone in person beats your face in because it's obvious mommy and daddy didn't discipline you enough to where you know better who NOT to piss off.
