As of right now, this is a straight copy of the deck by Chuubii
Copied Strategy:
Trying to make an aggresive Ninja Deck. The idea is pretty simple - start with low cost creatures like Augury Owl & Faerie Miscreant to cheat in ninjas. These two flyers also provide great card filtering/draw.
Once they are in I use enablers like Slip Through Space & Aqueous Form to continue bouncing/drawing/tutoring.
Hands of Binding are there to slow enemies down and, if ciphered on Mistblade Shinobi it can easily lock 2 enemy creatures out of the game. You can cast Hands of Binding during you pre-combat main phase, cipher it and attack; thus getting 2 instances of this effect.
Veil of Secrecy/Quickling are there to protect me against removal, as Hands of Binding + Mistblade Shinobi can take care of creature spells easily. I might suggest switching out Veil of Secrecy for Negate.
Testing Walker of Secret Ways - I am trying it out because of an interesting combat trick:
You have Walker of Secret Ways in play and 2 other creatures - a ninja and an enabler (for example Mistblade Shinobi and Zephyr Sprite).
Attack with both and lets assume Mistblade Shinobi is blocked, but the other creature isn't.
Now you can use Walker of Secret Ways's ability to return Mistblade Shinobi to your hand.
Use Shinobi's Ninjutsu ablity to switch him with the unblocked Zephyr Sprite.
Now you have done damage with Mistblade Shinobi, even though he was blocked.
This, of course, works with all of your ninjas.
Why not just bounce him back with Walker of Secret Ways and "ninjutsu" her in without all the screwing around? Sometimes your opponent has a creature that can block your enablers and you won't be able to "ninjutsu" in. This way, either he blocks your ninja and you do the trick or he blocks your enabler and ninja hits by itself.
