Vintage U fish with less agro and more control
Based on the more old school approach of using vials and chalice of the void.
I used to play a similar deck back in 2005-2006 with 4x Wild Mongrel, 4x Basking Rootwalla, 4x Flying Men and 4x Ninja. Very aggressive and very good at beating power heavy deck. Especially with the Mongrel + Gush finishing combo.
The only deck I had problems against were Oath decks, but with a little luck it could be done. Completely ate up Gifts Ungiven and Perfect Storm back in the days. I decided to make a new built based on the familiar and the snapcaster mage (which is probably one of the most powerful blue creature cards I have ever seen). You all of a sudden have two recalls and two time walks in your deck, plus you can summon up Flustorstorm if needed.
Basic strategy of the deck:
Typical starting hand:
Island, Wasteland, Daze/FoW, Vial/one-drop, Chalice, something, something.
Always make sure that you can drop a Chalice for zero if you start, otherwise, make sure you have a FoW if opponent goes first.
Turn one: Always make sure that you can drop a Chalice for zero to slow down your opponent. Either drop a Vial or one of the one drop creatures, if the lotus or mox is present, drop that aswell before the Chalice for 0.
Turn two: go directly to attack phase, attach with your one drop, ninjutsu, deal 2 damage and draw a card. Now you have your draw engine on the table, and you can start to control the table.
Turn three: go directly to attach phase, swing for 2, draw card. Play spells accordingly, but you should have many means of control at this point. Once you feel your have the board control (more and stronger creatures than your opponent), drop a standstill and watch your opponent frown.
If you have the vial on the table along with a standstill, you're in a good place. Being able to cast a Mage around standstill, making a recall ready before even breaking the standstill to draw a total of six is a very powerful defence even against the very heavy control decks. Even a vial for 1 and a surprise bird to counter an opponents desperate draw attempt is very powerful.
Once you understand the dynamics of this very simple deck, you start to understand just how powerful these cards are in combination.
You might want to consider different sideboards depending on your meta, but if your biggest fear is stax and dredge, then this should work quite well. Mirror against dvelver and MUD is tricky, so get the Jitte on the table as quickly as possible. With some luck you should however retain board control with more draw into counterspells.
Have fun!
