Turns and synergies

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

 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

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)

Chandra, Flamecaller and Elemental Bond

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

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.

play a couple of Cumble into Dust then Oblivion Sower

 Eldrazi Displacer+  Training Grounds+  Drowner of Hope

Eldrazi Displacer+  Training Grounds+  Drowner of Hope

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

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)

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

grimgrin - corpse born + grave crawler

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.

 Eidolon of Rhetoric +  Possibility Storm

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

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.

 Archmage Ascension +  Forgotten Creation looks fun
