Multiplayer ElfClamp

[JamesPr]

This deck can consistantly have It's entire deck on the table by turn 5.  Even though Skullclamp is an obscenely broken combo in this deck with priest of titania, this deck still can function to a high degree without skullclamp.

4x Llanowar Elves
4x Fyndhorn Elves
4x Quirion Ranger
4x Seeker of Skybreak
4x Priest of Titania
4x Wellwisher
4x Wirewood Herald (The tutor of the deck)
4x Timberwatch Elves
2x Heedless One
1x Wood Elves
1x Elvish Pioneer
1x Elvish Lyrist
1x Elvish Scrapper
1x Birchlore Rangers
4x Skullclamp
3x Hurricane
2x Concordant Crossroads (This ensures I win the turn I play skullclamp with a Priest of Titania.
4x Land Grant
8x Forest

The explanation of the combo is this.  I play Priest of Titania (By drawing or searching with wirewood herald via skullclamp), I play skullclamp.  I play a bunch of other elves.  I clamp the other elves into more elves and continue clamping until I have about twenty elves on the board with a hurricane in my hand with a concordant crossroads in play.  I tap wellwisher gain twenty life then hurricane everyone for twenty.  It works like a charm.  The one's of elves are for stability and they work well.  When I'm comboing wood elves let me play another land, elvish pioneers let me play another land, Elvish Lyrist, and Elvish Scrapper allow me to remove anything pesky stopping me from comboing.  Birchlore Rangers is in there because without a crossroads it allows me to tap elves with summoning sickness for quick mana.

Although your deck looks solid, most people don't like "turn 5 sweep all other players" decks in multiplayer...

[Sarcasmic]

Priest of Titania + Elves +  Staff of Domination = Everyone hates you.

As long as you have 4+ elves, the Staff gives infinite mana.  You will then control the board with your Staff.

[Redmage2k]

You will then control the board with your Staff.

Out of context quotes aside...
You should consider using Wirewood Hivemasters. Comboed with the Clamp they are just disgusting.
Bloodline Shaman is also very efective with the Seekers of Skybreak.

I have an ElfClamp variant that's a little bit more sociable than this and which is good for brutal amounts of overkill. It doesn't emply the gross mana generation route, although it does have the capacity to generate gross amounts of mana. I'd rather tap/untap a Timberwatch Elf repeatedly and use it to power through an enormous Llanowar Elite. I've added Faces of the Past to ensure that this is always possible. Every time I clamp an elf for more cards, I also get to untap all of my other elves. I also pack Rolling Thunder for board control and as an alternate win condition.

4 Llanowar Elves
4 Birchlore Rangers
4 Quirion Elves
2 Priest of Titania
2 Wirewood Channeler
4 Quirion Ranger
4 Llanowar Elite
4 Timberwatch Elf

4 Skullclamp
4 Rolling Thunder
4 Faces of the Past

3 Mountain
6 Island
11 Forest

There are only a handful of non-standard choices in this deck, which I'll address:

I use 2x Wirewood Channeler in place of two more Priest of Titania to help alleviate colour-screw. Although Birchlore Rangers and Quirion Elves usually prevents colour-screw just fine, a couple extra Wirewood Channelers provide a little extra protection, while offering the same big mana boost as Priest of Titania.

Timberwatch Elf is probably not the preferred way to win with an elf deck, but since I built the deck around Faces of the Past, it seemed like a good choice. Besides that, it's always amusing to get an elf pumped up to 80/80 or some other such obscene size.

Llanowar Elite are simply the right creature to couple with Timberwatch Elf. They're strictly superiour than Defiant Elf. It's important that they have trample since the combo can't always continue, since it kills its combo pieces as it goes.

Faces of the Past is the cornerstone of the deck. It may not be the best card around which to build an ElfClamp deck, but I was forced to use it by kharmic pressure. Anytime I open the same rare more than once, It's a sign from above that I have to build a deck around that card. Even if it's a crap rare. Especially if it's a crap rare. (Ask me about my Living Hive deck.)

What's your living hive deck?

[Ephraim]

It's a Tooth and Nail deck built before anybody knew there was such a thing as Darksteel Colossus. Who needs an 11/11 indestructible creature when I can bear down on my opponent with a 6/6 (sometimes 14/14, thanks to Accelerated Mutation) trampling insectoid elemental that generates enormous swarms of insects? Oh, I musn't forget Kamahl, Fist of Krosa, to make all of those insect tokens truly formidable, when I have seven or eight opponents to kill.
