Turns and synergies

[MuggyWuggy]

Loving oblivion sower with nissa on field, guaranteed to get you ahead in the mana game or draw game

[mickeven]

 {Gisela, Blade of Goldnight} +  {Satyr Firedancer} +  {Repercussion} have pretty sweet synergy. {Lightning Bolt} opponent for 6, Satyr deals 12 to a creature that player control, Repercussion deals 24 to that player. so 30 damage from a Lightning Bolt to a player

[Kaylesh]

{clone} a Colossus. ({darksteel colossus}/{Blightsteel colossus}.
Should the copy die, you get to shuffle the cloning card back into your library, since it still has the replacement ability when it's checked. (Just before entering the yard)

[Oldschoolmtgnoob]

{Chandra, Flamecaller} and {Elemental Bond}

Came up together in my deck as a happy accident and was very useful.

[Thefluffymacheen]

I run {Satyr Firedancer} with {Searing Blood}

2 to a creature (make sure it dies) 3 to the player, firedance says ok and throws another 3 at a creature

had not thought about getting some Gisela action in there...

I actually pulled this off today xD.

[imFourth of Phils]

play a couple of {Cumble into Dust} then {Oblivion Sower}

[Controlfrk]

 {Eldrazi Displacer}+  {Training Grounds}+  {Drowner of Hope}

[Kaylesh]

{Eldrazi Displacer}+  {Training Grounds}+  {Drowner of Hope}

That seems like a nice way to get infinite mana/creatures/etb & die triggers.

[Kaylesh]

{Immerwolf} + {geier reach bandit} seem great pals.
Never have to worry about flipping your wolves.

(Transformed bandit lets you transform your weres as they enter)

[Kaylesh]

Swing with {Kurkesh, onakke ancient},  equipped with {Grafted Exoskeleton} and {Whispersilk cloak}.
Activate {Contagion Engine}, copy for {R}.

[Subiskier]

{grimgrin - corpse born} + {grave crawler}

[Kaylesh]

How to shut down a game.

While having {confusion in the ranks} and {pyromancers goggles}, cast {Thieves' auction}(with the goggles for a copy). In response use {voltaic key} to untap the goggles, play {fork} targeting the auction.
Now you've got 4 thieves auctions on the stack.
If not all your opponents have folded by this time, have your first pick be CitR for each auction.

[Thefluffymacheen]

 {Eidolon of Rhetoric} +  {Possibility Storm}

Each time they play something, they cannot cast whatever they get with possibility storm, essentially countering all spells played.

[Indianslayer]

{Eidolon of Rhetoric} +  {Possibility Storm}

Each time they play something, they cannot cast whatever they get with possibility storm, essentially countering all spells played.

Change Eidolon for {Curse of Exhaustion} so you can still cast things but the opponent you chose cannot.

You could also change Possibilty Storm for {Knowledge Pool} and still get the same result.

[mgrenier25]

 {Archmage Ascension} +  {Forgotten Creation} looks fun
