Good Game. You got your rulings mixed up. Malefic Stardust Dragon is a condition not an effect, therefore i could only have one. You did say you can't which is correct, however its a condition not an effect so Skill Drain can't negate the more than one Malefic effect.

Also you had to ask me to explain skill drain, however i assume you have learn't some new rulings from this duel which is what i want my students to do.

You therefore have been placed in Slifer the Sky Dragon, post your dorm when your ready. I suggest you keep a close eye on the classroom, articles and pro deck-lists to help you improve and become the best duelist you can be.

This has been your free Preliminary test, from now on you need to buy a Test Item from the Academy Main Shop.
