Yeah, i understand that is not the best strategy, but it's fun.
For
you it is fun. The deck you are trying to build/run is designed to win by making your opponent sit there and
slowly wait for you to achieve a win condition, is it not? When it works it is just fancy solitaire. Now, if this deck is meant to be competitive and you think it is the best play, I won't fault you for using it to try and win tournaments: competitive play is competitive. If it is just "for fun" though, make sure you've got opponents that agree with your idea of fun.
Yes I am aware that some people quite enjoy trying to win a "no win" situation by waiting for a convenient draw and/or an opponent's misplay/bad luck. Most of the time however I am not one of them and it is especially annoying to encounter in timed play.
With that said, I must advise some caution; in Expanded your opponent has multiple options to break the lock. If they are one of the decks that run
Bunnelby (Ancient Trait version) then when your deck gets low you risk having your combo broken via discard. They might not deck you out (though if you rip through most of your deck and are using
Mew-EX top copy
Accelgor's attack, that is possible as well) but whiffing on reinstating the lock can still easily cost you the game, but the
big risk are people that just know how to deal with your deck. Now it goes from wondering about your opponent having fun to wondering about you having fun if your opponent can lock down or otherwise deny Abilities, Evolutions, Items, Special Energy and/or Stadiums or simply set up
just as fast as you do and can steam roll you (possibly with weenie sized attackers you can't help but OHKO, thus breaking the lock).
Decks such as Accelgor and the Musharna deck that is being discussed are still able to do it since they have ways of putting cards back into the deck so that you don't deck out. Note that you can't deck out the following turn by drawing if you attacked with either Accelgor or Musharna. Of course if for whatever reason, you can't attack, then your opponent might be able to force you to deck out, but against a lock deck such as Accelgor, there's not much you can do to make them miss Deck and Cover once they get set up.
Depends upon the exact version of the deck; the generic tactic was to just wait for the opponent to take enough Prizes and then hit them with
N as it usually shuffled their large hand back into deck, leaving them desperately trying to get their next attacker out. Specific decks will simply shut down some vital element; the game has a crazy pace right now. Though this "attacking with Musharna" has me confused. I remember it being used for its Ability, not its attack. Have I goofed and am commenting on a version of this deck I don't know? >.>
