I've liked the idea of stacking Rajan's Furies and Marked for Death and making powerful falcon attacks since I saw the swarm build posted by DeckBuilder, but I was never satisfied with that build. It has enormous redundancy, but no contingency for dealing with someone with strong counters to swarm play.
Here is my current iteration of trying a build that can make the same kinds of plays, but with more diverse strategic options. In matchups where I don't see a Thunderdrift Falcon swarm performing well, I can use some combination of Valshalla, Cervere, Emerald Tegu, and Highland Unicorn, and support them with nature enchantments and Wand of Healing. I need to refine this build a bit more, but I wanted to post it's current state.

I'm planning on replacing the Decoy with Lion's Savagery when FiF hits. I would like to replace Geyser with Surging Wave, but all of my Surging Waves are tied up in Blood Wolves at the moment.
I have 3 Acid Balls, 3 Marked for Death, and 2 Rajan's Furies to support the damage output of a swarm, and I have Highland Unicorn to heal them. I toyed with using Shift Enchantment + Fortified Position, as was used in DeckBuilder's build, but ultimately decided that including that was too big of an investment to justify, particularly with the cost in game to make proper use of it.
I use Emerald Tegu because I'm trying to have as little creature overlap as possible in my 3 BM builds, and my other Straywood build runs Timber Wolf. In particular, I'm going to want to swarm against the Necromancer, who tends to be weak to flyers, so I'll probably be using either a Falcon or Unicorn Pet in the matchup where Emerald Tegu is weak.
The matchups where I would be hesitant to swarm Falcons are Bloodwave Warlord (Veteran gives him a strong late game against swarm, whereas he might never benefit from it if you play only a few creatures), Wizard (Arcane Zap and Wizard's Tower spamming Jet Stream will shred Falcons, plus Suppression Cloak will slow you right down), and the Druid (Kralathor becomes an absolute monster after eating a swarm). Beastmaster's can run Kralathor, but it's less common. If only fire spells didn't cost triple I would consider running a couple of Fireballs or Flameblasts to take out Kralathor.
