I posted a pike list a while ago, I was not too happy with it though because I don't like having to get lands, or really getting any new cards anymore. I don't play often enough for it to be worth it. I thought up this list though, and I like it because it has ninjas.
Withdraw would be wrong for me not to use, as I suggest it every time someone posts a ninja deck :P Arcane denial is because I love it and gives extra thopters something to do, and I think the rest is self-explainatory.
Phantasmal Bear might be better than Delver of Secrets , if you're going to be returning him often anyway. Plus then you can scrap Ponder , which only seems very useful for setting up Delver. In your deck Delver only has a third of a chance of flipping on his own also.
I am not too big on the bear because of his lack of evasion, and I like ponder for pike fuel anyway, but I might end up returning him a lot, so I think i'll test for that. As for the snap/withdraw thing, I like how withdraw can work as Undo , I am using all my snaps already, and I suggest withdraw with these kinds of decks enough where I want to try using it for myself.
Arcane Denial i'll probably end up cutting, I just have a burning love for it. Same with the fathom seer actually :3
It also occurs to me that mistblade shinobi is not great here, since I get my guys through by using bounce and if I bounce their guys to get through he will not have any targets, so maybe 4 is wrong, 2-3 might be better. I could also use Artful Dodge which likes my thought scouring.
In a Pike deck I'd use Shadow Rift over Artful Dodge . Artful Dodge is only at its best if you flash it back, and then it's exiled.
Also being a 2/2 on turn one is pretty evasive, I mean not much is going to block it. You also have the Ornithropter . Delver is fine, but like I said, if you run Delver then Brainstorm is probably preferable to Ponder .
I think I am actually going to use Snap instead of the vapor snags in here, because I think I will end up bouncing my own guys often enough, and the snags will work fine in the other deck. I will also cut the denials and one mistblade, I have a single shadow rift I can throw in, and I'll think on what I want instead for the last two slots.
