So… Faeries!
Spellstutter Sprite is a good reason for doing this as it provides a highly disruptive creature for a cheap mana cost. Cloud of Faeries allows us to deploy Spellstutter Sprite on turn 2 with multiple Faeries in play, whilst the cycling ability gives us a little velocity if we need to dig for answers. Another cheap enabler for Spellstutter Sprite is my new Magic: Origins card.

Faerie Miscreant is a little on the weak side in a vacuum, but it is surprisingly powerful in this deck. We are looking to churn through the deck as quickly as possible and having a 1/1 flyer that draws a card when it enters the battlefield for one mana is a strong consideration. With this in mind we can create a suite of cards to re-use both this and the Spellstutter Sprites by bouncing them. Both Faerie Impostor and Quickling give us two power flying bodies – with the Imposter being cheaper, allowing us to deploy more threats more quickly, but the flash ability on the Quickling being useful to save creatures from spot removal or even allowing a ‘block and bounce’ to happen.

Our other creature bouncer is Ninja of the Deep Hours. When you bounce an attacking creature that lets you draw a card when it enters the battlefield and swap it in for a creature that draws a card when it deals combat damage to a player, you can see how much of a card draw engine we can create in this deck.

Speaking of card draw engines, we come to the uncastable card: Sky Hussar. The Hussar allows us to turn our small cheap creatures into even more small cheap creatures, into free Counterspells and removal in the form of Foil, Daze, Thwart and Snapback. On every turn we can get us an extra card for each copy of Sky Hussar we draw and once our hand gets too full, we can start discarding creatures to allow us to cast our finisher: Skaab Ruinator.

The deck is nicely rounded out by some other disruptive creatures. Personally I feel that Martyr of Frost is a little underplayed in Legacy. Whilst is it a fragile body that dies to a stiff breeze, the ability to get Counterspell on legs down and attacking for value is certainly not to be sniffed at.
I am fully aware that the threats in this deck are all rather weak. Only the Ruinators can close out the game with any degree of reliability and every other creature dies to basically any other removal spell in the game. However, it is the speed with which we can deploy these creatures and the amount of them that we can cast whilst still being disruptive that gives us a lot of game against most decks.


Our sideboard is a mix of powerful hate cards and specific, narrow, cheap counters that can give us game in difficult matchups.

Ghost Quarter, Back to Basics
These two cards are great to bring in against a wide swathe of the format, putting further constraints on our opponent’s mana. These are also likely the games where Ghost Quarter are likely to be strong, so we have another two of these available – as well as to help against taxing decks that will attack out own mana.


Envelop
This one is pretty much solely for Show and Tell. There are other targets for it out there, but this is such a large part of the metagame right now that we have to make these kinds of concessions for such a powerful deck.


Ivory Tower
This card comes in against Burn decks as it allows us to gain stupid amounts of life for little initial investment.

Disrupt, Phyrexian Revoker
This one can also be good in the Burn matchup as a way of clearing out their own threats and using their bomby burn spells like Fireblast against themselves, but that is really there to protect our creatures and hand against Abrupt Decay decks and their discard spells.
Phyrexian Revoker gives us another disruptive body that can be difficult to use properly in game one but in game two in can be brought in for matchups where it is a veritable sledgehammer against certain specific decks.

Tormond's Crypt
Finally we have Tormod’s Crypt for the graveyard reliant decks. There’s not much to be said for this in terms of any tricks you can do with it, it does the same job it does in any other sideboard.
