Mono red midrange aggro control deck.
The primary strategy is to play an early lock piece (Trinisphere, Chalice of the Void or a moon effect) to slow the opponent down and then attack with Goblin Rabblemaster and Shaman of the Great Hunt to finish the game before the opponent can find an answer to the lock piece. Most our creatures have haste, so we can be very fast (theoretically a turn 2 kill is even possible :-)). Goblin Rabblemaster and Shaman of the Great Hunt are the core of the attack team.
I have tried to add a lot of cards that generate card advantage (the "red" way, i.e. with 2-for-1's), in order to have a later game. Goblin Rabblemaster, Pia and Kiran Nalaar, Fiery Confluence, Chandra, Torch of Defiance, Thopter Engineer, Koth of the Hammer and Arc Lightning from the board each provide card advantage of some sort. This works particularly well against delver decks: by playing around Daze you can outgrind them in the later game.
Dead/Gone is to get rid of larger creatures (at least for a turn) by bouncing them (especially effective against Marit Lage tokens and to a lesser extent Gurmag Angler). The dead-part is a bit of a nonbo with chalice @1 but often enough you don't have a chalice out and you can kill a small critter with it.
Death and Taxes is a tough matchup, so I have a lot of sideboard cards for this matchup.
Sneak and show decks are also tough. The strategy against these decks is just to be faster (and maybe generate enough tokens to survive one Emrakul, the Aeons Torn hit).
Sideboard:
Leyline of the Void for graveyard hate.
Fiery Confluence is great against artifacts, provides mass removal for lots of small creatures and is also good for 6 damage in the face (even bypassing Leyline of Sanctity and friends).
Sulfur Elemental against DnT and other white weenie decks (especially Thalia, Guardian of Thraben is annoying because is has first strike and our creatures are x/2 or x/1). It is also great against Monastery Mentor.
Abrade is a good new addition against DnT.
Dead/Gone additional "removal" for big creatures.
Null Rod against equipment and against storm (shutting down artifact mana).
It all works quite well, although the deck has trouble dealing with big creatures such as Tarmogoyf. Dead/Gone helps a bit, but not enough. Maybe add some Ensnaring Bridges if they get less expensive.
