1 – jitte
2 – mind twist
3 – ajani vengeant
4 – Library of alexandria
5 – sol ring

On to my list:

1: Umezawas Jitte: The best equipment ever printed. Evan said it best when he said this was a creature dominated format, and Jitte dominates creature combat like nothing ever printed.

2: Sword of Fire and Ice: Giving your best creature added size and protection from Cryptic Command and Trechery from the control decks and Lightning Bolt, FTK and Incinerate from the aggro decks makes this card nuts.

3: Recurring Nightmare: An amazing way to abuse some of the Cubes most powerful creatures. Everything from Siege-Gang Commander and Deranged Hermit to Shriekmaw and Bogardan Hellkite can go from awesome to game-ending in the drop of a hat.

4: Bitterblossom: Combines nicely with my top three picks as well as other busted cards like Skullclamp and Mycoloth. It also allows control decks to turn the corner without tapping out and can provide some early-game defense.

5: Trechery: One of the biggest tempo swings ever printed. Turning their best blocker into your best attacker is pretty nice. As is stealing a creature with a game-breaking ability like Reveillark or Numot, The Devastator.

Honorable mentions:

Profane Command: One of the best limited cards ever.
Cryptic Command: Awesome in 2HG… And everywhere else.
Plow Under: Its game over if your winning.
Venser, Shaper Savant: Seemingly the best of the blue dorks. Flexible.
PLANESWALKERS: They cast free spells. Thats good, right?

#1: Venser- I love this guy so much. He blocks and bounces or counters. He is the answer that the decks I draft need for manlands or the early Savanah Lion-esque creatures. The tempo gain from bouncing a karoo is also huge.

#2: Obelisk of Alara- In control, it’s hard to lose after resolving this card. You don’t even have to wait a turn before activating it, just play it with mana up. I have literally not lost after resolving this and keeping it for more than 1 turn. Not many decks can race 5 life a turn.

#3: Cryptic Command- I am never scared of anything when I have this in hand.

#4: Sword of F/I- My favorite first pick. It leaves you in any archtype, and is awesome in all of them.

#5: Desolation Angel- I played with this for the first time last draft, and I also had Treachery in my deck. Twice I had 4 lands and a karoo in play, tap for 6, play treachery untapping my karoo with one mana floating and then cast Desolation Angel. It’s a blowout on a stick. (Just don’t reanimate it)

2- Debt of Loyalty. If you are in white, this is the best card in your deck. Period.

3- Wash Out. Our play group was testing with this card and it gives blue exactly what it needed: a turn 4 reset button against aggro.

4- Goyf/Tog. Pretty obvious why.

5- Force of Will. Says no to broken situations.

The obvious first pick is Mana Vault/Sol Ring. I am still undecided on which is better, Sol Ring is far more reliable, but also the difference between 4 mana and 5 mana on turn 2 can make a huge difference to how the game plays out. My personal favorite is Vault though.

(Taking out the obvious power cards >.>)

2) Sol Ring
Unlike everything else on this list, this card is nearly insurmountable and puts you two turns ahead. I cut it from my cube for reducing games to opening hands.

3) Treachery
Huge swing in CA and tempo.

4) Bribery
The best creature in your opponent’s deck for 3UU. You usually end up with a Kokusho/Akroma etc that’s a pain to answer and should cost way more than 5 mana.

5) Jitte/Survival of the Fittest/Recurring Nightmare
Overwhelming advantage in combat. ’nuff said.

Library and Divining top are strong, but I have a relatively ‘fast’ cube which makes their tempo cost more limitting.
