Hey all, after kicking around the idea of a Legacy Bear deck, I thought it would be fun to have a thread where we could list decks, look 'em over, and compare ideas for improvement, so without further ado, here is:

Elf Sex (Casual tribal deck by DocTwisted)
Lands:
18 Forest
1 Sapseep Forest
1 Wirewood Lodge

Creatures:
4 Essence Warden
1 Joraga Warcaller
2 Wirewood Symbiote
4 Priest of Titania
2 Seeker of Skybreak
4 Wellwisher
1 Elvish Archdruid
3 Elvish Harbinger
1 Ezuri, Renegade Leader
1 Imperious Perfect
2 Jagged-Scar Archers
1 Titania's Chosen
4 Winnower Patrol
1 Glissa Sunseeker
2 Heedless One
1 Lys Alana Huntmaster
1 Ambush Commander

Not Creatures:
1 Elvish Promenade
1 Primitive Etchings
1 Predator, Flagship
2 Recycle

If this deck is left alone for a bit by the other players, it turns into the kind of wild Elven orgy that Tolkein slashfic writers always dreamed of. Life is gained at alarming rates, cards are drawn and played rapidly, and new Elves just pour out of the woodwork (pun intended). There's several "if I draw this guy I can win" cards in the deck, and 3 Harbingers to fetch them. Add to that the 2 Wirewood Symbiotes, and you can tutor for a fresh elf each round!

Love it! It actually looks quite a lot like the green-black Elf deck in M:tG: Duel of the Planeswalkers 2012. Which is a scary-good deck.

Okay, now for a really swingy combo deck I built. I call it:

"It's Great When It Works!" (A bonus Internet to the first person to recognize the quote.)

Lands:
14 Island
4 Mountain
2 Lonely Sandbar

Creatures:
2 Augury Owl
2 Merfolk Traders
2 Psychic Membrane
3 Sage of Epityr
4 Sage Owls

Spells:
4 Accumulated Knowledge
2 Ancestral Knowledge
1 Ancestral Vision
4 Arcane Denial
1 Impulse
4 Mana Severance
2 Treasure Hunt

Artifacts:
1 Crystal Ball
1 Darksteel Pendant
4 Goblin Charbelcher
1 Sapphire Medallion
2 Skullclamp

The whole deck is designed to find a Goblin Charbelcher, a Mana Severance, and the mana to use them both as quickly as possible. Ideally, you can play the Goblin Charbelcher on turn 4, then on turn 5 play a land, Mana Severance for everything but one Mountain, then activate the GC for massive damage. Note that this almost never happens. Also note that once your opponent(s) have seen this kind of deck once, they will know what to watch for to stop it, or in group play will sound the alarm and have everyone kill you before the doomsday device activates.
