A Six Samurai Synchro Monster...interesting.  Legendary Six Samurai-Shi En is a Level 5 Synchro Monster, of the Dark attribute, Warrior monster, with 2500 attack and 1400 defense.  Synchro Summoned with one Warrior Tuner and one or more Six Samurai monsters.  Easy enough being Level 5 I believe.
 
Now, once per turn when your opponent activates a Magic or Trap card, you can negate said cards activation and destroy it.  It doesn't have to be the first card, so that's a bonus.  It adds some versatility to this card, which is nice.
 
Furthermore, when this card would be destroyed, you can destroy another Six Samurai mosnter you control inated.  A nice bit of protection helps too.  2500 is powerful enough, and Level 5, even with specific monsters won't be difficult.

Today’s Card is Legendary Six Samurai - Shi En. Shi En is a pretty broken synchro monster. First off, this card is incredibly easy to summon with the Samurai deck; they have their own 3 star Boggart Knight and their little 2 star tuner making bringing Shi En to the field almost guaranteed any match. I like the fact that this card has 2500 Atk, meaning it can get over Monarchs and other synchros like Magical Android. What really breaks this card, though, is its ability to negate your opponent’s spells and traps once per turn. Not only can this card negate kill cards, like Smashing Ground, but it can negate searching cards and draw power cards as well, like ROTA and Charge of the Light Brigade. Shi En also comes with some build in defense, so if you need to keep him around, you can just blow off another samurai you control.

Today is one of the new Six Samurai monsters. Who saw that coming? This monster is a strong, level 5 synchro monster, whose effect is good too. Its effect states that once per turn, if your opponent uses a spell or trap card, you may negate and destroy it. Its second effect is the generic six samurai ability to destroy another six samurai instead of it. It being a level five synchro has its advantages too. Using the Six Samurai version of Boggart Knight, you can special summon the level 2 tuner from your hand to synchro straight into this big 2500 attacker. As I hope you have seen, this card doesn’t really have a weakness.

Legendary Six Samrai - Inishi

All I can say about this new syncro is WOW! What was Konami thinking about creating such a powerful card? I know it's a specialized card for Six Samrai decks but come on! Look at all the it has going for it.

• It's a level 5 with an attack of 2500, which is nothing to sneeze about. It can get over other powerful level 5 (Ally of Justice Catastor, Magical Android) with no problem.
• It can negate most trap cards that would stop it from coming into play (Bottomless Trap Hole, Trap Hole, etc.). Remember it can not stop Solemn Warning or Solemn Judgement. They negate the summon.
• Once on the field it's just about impossible to remove since it allows you to negate your opponents spells such as book of moon, enemy contoller, soul exchange, etc. And negate their traps such as dimensional prision, unflipped royal oppresion, unflipped royal decree and any non speed spell 3 trap.
• When it gets destroyed you can select another six samrai to take its place. This means in battle or any other ways it can get destroyed. So you can go toe-to-toe with another 2500 attack creature. Destroy their monster and keep yours by just destroying your weakest six samrai on the field.
  

The only down side I see is that you need "1 Warrior-Type Tuner + 1 or more non-Tuner "Six Samurai" monsters". Meaning you have to be playing a Six Samrai Deck. But if you are planning to play this card you are already playing a Six Samrai Deck. So there really is no down side to it. Just be prepared to see this syncro monster on your duel tables soon.

Shi En is basically the backbone of the new Legendary Six Samurai cards. He's a DARK Warrior, 2500/1400, level 5 Synchro Monster. You must use a Warrior-type tuner, and a Six Samurai non-tuner. He's essentially the younger, more virile version of Great Shogun Shien. Once per turn, you  can negate and destroy any Spell or Trap your opponent plays. This is a huge effect, which, when coupled with his second effect, makes Shi En very tough to take down. His second effect is the standard Samurai redirection effect. When he would be destroyed, you can destroy any other Six Samurai monster instead. As if it wasn't bad enough, you can even further protect him with the Samurai's new counter trap, Musakani Magatama, which is a costless Destruction Jammer while you control a Six Samurai.

Shi En is extremely easy to summon. Simply use Legendary Six Samurai - Kageki, a Samurai Marauding Captain, to bring out Kagemusha of the Six Samurai, the Six Samurai's tuner monster. You can also use Double Edge Sword Technique to bring him out quickly. It's very easy to search out Kageki and/Kagemusha, thanks to Gateway of the Six and Shien's Smoke Signal. You can easily and consistently be summoning Shi En on your first or second turn.

Being nearly impossible to take down, huge ATK points, and a part of a great archetype, expect Shi En to be making waves for quite some time.

Traditional: 2/5 Samurai might work here, but you'll probably just get FTK'd first.
Advanced: 5/5 This guy is the new boss of the best new deck we've had in some time. Watch out.
