Hiding in plain sight? That’s the job of members of this archetype. One may even call it an Art form…

Introduction:

Of course you have additional Ninjitsu Arts at your disposal as well, ranging from draw power and destruction immunity to ATK reduction, monster removal, and attack negation. At the end of the day, you have a ton of options. That is what Aggressive Ninjas is all about, abusing the insane search power and wide berth of the Ninja archetype to search out whatever answer you need, then continuing to generate even more free card advantage. Eventually, your opponent just won’t be able to continue trying to keep up. I think I’ve spent enough time talking about the potential of this deck, so let’s get into the Key Cards, shall we?

Key Cards:

• Ninja Grandmaster Hanzo
  • The ‘Active’ searcher of the archetype, you get to add a Ninja or Ninjistsu Art based on how you Summoned him. Or you could just add Duplication, then use a second Hanzo from your deck on the subsequent turn to search out a Ninja. 
• Twilight Ninja Getsuga, the Shogun 
  • The boss and first recursion threat of the archetype. Also, its Level works well with Duplication. Pretty strong if you ask me. If you need more reasons to run it, simply re-read the introduction paragraph about him.
• Twilight Ninja – Shingetsu
  • The ‘Passive’ searcher of the archetype, also lets you lock out your opponent whenever you get 2 of them to the field. A worthwhile addition to any deck, but a star in this Aggressive Ninja strategy.
• Earth Armor Ninja
  • The days of having just an inherent Special Summon are not over. Not quite! Earth will always be put to good use in Ninjas, even if it doesn’t have 4 different effects like some newer cards.
• Ninjitsu Art of Duplication
  • Special Summoning power from the deck; combo piece that is invaluable and irreplaceable.
• Reinforcement of the Army
  • Searcher for our searchers who then can search the other searcher which will search the other searcher and so forth. Yup, that makes complete sense.

Additional Tech Options:

This time around, the tech options are either more Ninja and Ninjistu Arts, or more supporting cards to help the Ninjas do what they do best. We did have a bare-bones Key Card section after all! Remember, your goal is to overpower the opponent with sheer card advantage and summoning power, never forget that!

• Red Dragon Ninja & Ninjistu Art of Transformation – The Level 6 Winged Beast Ninja never rides in a deck without its faithful Ninjitsu Art. This is an excellent choice when you want to disrupt decks and control their destiny.
• Black Dragon Ninja – A tech only to be considered if you are already running Red and Transformation. This lets you abuse the free searches from Hanzo and put all of the extra Ninjas in your hand to good use. Is it perfect? No, but it sure steps up doing a fine job when you prepare to fully overrun your opponent.
• Twilight Ninja Nichirin, the Chunin – An on-demand option for protecting your Ninjistu Arts and Ninja monsters from destruction. It also can fit in the deck easily as a one-of, instead of relying upon a large Super Transformation engine alongside White Dragon Ninja. This card just does it better. Also lets you run over powerful monsters such as Ultimate Falcon or Towers without digging into the Extra Deck.
• Ninjistu Art of Shadow Sealing – Searchable monster removal, while the removal isn’t necessarily permanent, it definitely can be useful in a pinch to get rid of monsters that pose a large threat to your continued existence within a duel.
• Armor Ninjitsu Art of Alchemy – Searchable draw power that makes good use of your leftover Ninjitsu Arts while also clearing space in your backrow. Note that this works best if you only have 1 face-up Ninjistu Art, so such as the moment right after you perform the Earth + Duplication combo described earlier.
• Magic Planter – The other draw-power option and way to use spent Ninjitsu Arts. The biggest different between this and Alchemy is that Planter is generic, while Alchemy is searchable. So you can still send your Call of the Haunted with this, but you will not have this spell available as often as you’d like.
• Call of the Haunted – I was tempted to put this in the Key Cards section, because additional summoning from the Graveyard really is that important. Simply revive a Hanzo to search out Getsuga, and you already have your tribute Summon all set to go.
• The Monarchs Stormforth – Sure, you may be running a large Extra Deck. But with a deck that is running many Level 6 and a couple Level 8 monsters, it always is something to consider. Non-targeting, non-destruction monster removal really is that great. Even if you don’t need to tribute a second monster for Getsuga, you still can if you want to get rid of theirs in the process. Also, as a last resort, you could even Tribute Summon Earth Armor Ninja.
• Allure of Darkness – You run a ton of Dark monsters, but have no way of recovering banished cards. If you want the extra draw power, by all means run this. 
• Senior Silver Ninja – Sure, he boasts a powerful effect. But in all honesty, his effect can be a bit slow. You should weigh your options carefully when deciding whether or not your deck could use his help.
• Strike Ninja – This deck can be modified to be very reliant on DARK Ninjas and them alone, abusing Hanzo and the Twilight Ninjas rather effectively. You would also need to be running banish retrieval, such as Escape from a Dark Dimension. This build is a bit gimmicky, but it is an option nonetheless.
• Karakuri Ninja mdl 339 “Sazank” – Interested in summoning out this guy with Duplication or Senior Silver? Remember, Duplication can summon him in face-down defense position if need be, so he is on-theme and on-call monster removal.
• Masked Ninja Ebisu – Boasting an effect to spin away any backrow threats, Ebisu is a good Ninja for ensuring your OTK attempts go through. Sadly, he doesn’t actually gain any tangible card advantage, which is why he’s relegated to Tech Option status.
• Crimson Ninja & Armor Ninja – The Level 1 Ninjas that you can choose to run to offset any slight differences between Duplication and the Ninja you tribute. Also, these double as great things to Special Summon back with Senior Silver since he Summons in face-down defense, perfect for FLIP monsters.
• Upstart Golden Ninja – Once, he was the prime deck Special Summoner. But let’s face the facts, trading away a Trap for that Special Summon really wasn’t worth the effort, especially when Duplication does that job better while also providing other roles. But if you want a bit more utility in what cards you can search, this is an option for you.
• Blackwing – Zephyros the Elite – Great for reusing those Ninjitsu Arts that happen to be laying around. Also is a Level 4 Winged-Beast who can be pulled out of the deck with Transformation.
