If you have no time for noobs, you shouldn't waste time telling noobs you have no time for noobs. ;p Lol.
Ben10, there is a ruling with Neo Ocean Lord - Daedalus that you have to offer
Levia Dragon - Daedalus to special summon it (just like with
Vampire Genesis and
Dark Eradicator Warlock) - it's a rule, and people play by following the rules.
For all you naysayers about 'BANNED CARDS', there is a format called TRADITIONAL, and there are tournaments that feature the Traditional format. There's also a format called SUPER BANNED, but I won't get into that now. ;p
And him throwing the
Turbo Cannon in his Extra Deck is
fine, even if he CAN'T use it - it throws the opponent off, maybe.
If his deck works for him, and his friends let him play with the Levia the way he feels he should be able to, there shouldn't be any problems.
More power to ya, Ben10. My only suggestion would be to buy some of the newer structure decks so you'll have more cards - the newest decks have some REALLY powerful cards.
