I always wanted to build a Sneak Attack deck. But I also love to make things more difficult for myself. It doesn't get much more difficult than a RW Zirda, the Dawnbreaker Sneak Attack deck.

The primary game plan is simple:
1) If you don't have Sneak Attack, Purphoros, the Bronze-Blooded or Feldon of the Third Path, tutor for them using Enlightened Tutor etc.;
2) Activate a Sneak Attack ability and put a threat onto the battlefield; and
3) Flicker the threat with a flicker spell/ability (Ephemerate, Eldrazi Displacer, Livio, Oathsworn Sentinel ) or exile it with Mimic Vat.

The deck is also often able to cast the threat for the full cost, mainly via Alena, Kessig Trapper, Mana Geyser or Treasonous Ogre. You also have access to infinite mana thanks to Zirda, the Dawnbreaker + Basalt Monolith, Alena, Kessig Trapper + Staff of Domination or Mana Geyser/Jeska's Will + Reiterate.

If the Sneak Attack route or the infinite mana aren't working, you can always tutor up the good old Heliod, Sun-Crowned + Walking Ballista combo; the Walking Ballista acts as an infinite mana outlet as well.

In order to execute your gameplan, you should lay low for the initial turns until you have your hand set up. The deck has very limited options for drawing cards, so protect your draw engines and try to keep up Reiterate and Reverberate for any potential big blue draw spells your opponents cast.

Tips:
1) Use bouncelands (Boros Garrison etc.) to return land MDFCs (Valakut Awakening // Valakut Stoneforge) to reuse them in later turns. They also work well with Weathered Wayfarer.
2) Always try to cast Alena, Kessig Trapper early, she leads to broken plays and gives you access to infinite combos.
3) Never overextend! Plan for explosive turns; the first 5 turns are for setup only.
4) Deflecting Swat, Reverberate & Reiterate are the most versatile spells in the arsenal, so save them as long as possible.
5) Use Livio, Oathsworn Sentinel as a political tool to survive the early turns.
6) Axgard Armory can search for an Equipment and an Aura. The only aura in the deck is Footfall Crater, so keep that in mind.
7) Field of Ruin, Path to Exile and Winds of Abandon are ways to turn on Weathered Wayfarer's ability.
8) Fetch snow basics (and Alpine Meadow) first for Field of the Dead and Search for Glory.
9) Remember to fetch for Mistveil Plains (it's a Plains) to reuse spells tutored with Sunforger.
