Zedruu the Greathearted (EDH / Commander)

IT IS NOT A GROUP HUG DECK!!!!

Trade your weak permanents, mostly the have a big drawback (for their controller), with your opponents. If they don't want Zedruu is going to make them a present anyway.
Protect Zedruu, draw cards and gain some life; meanwhile you can be an annoying bastard, by slowing down your opponents or lock them completly with cards like "Pyromancer's Swath", "Statecraft" or "Celestial Dawn".
A well timed gift of "Delaying Shield" can retourn lethal damage, or one of my favorites is to make someone lose 20 lifes with "Illusions of Grandeur" after you just got 20. :D
Much more fun is to exchange your "amazing" permanents with "Puca's Mischief". Take away the mana base or whatever you need most, or whatever your opponent shouldnt have.
You are almost never going to run out of cards to give away, because you can give away the control of cards like "Oblivion Ring" or "Hobble" to make them even more useful.
To close this circle you can use "Venser" to get back your permanents on your side.

Finally you win by getting the control of the board, or with plenty of pegasus tokens, luckily you have mostly a lot of life gain.
Sadly your library contains not infinte cards, but with a little imagination ("Mistveil Plains", "Jötun-Geiferer", "Vessel of Endless Rest") or much simpler mill someone in before his drawstep with "Psychic Spiral" and you get ride of two problems at once.

This deck doesn't look like it has serious chances to win, but, specially in multiplayer games, it's soooooo much fun and surprisingly effective.
