I think 4 Incinerates and 4 Fire/Ice are the best of that choices.
By Brian Epstein (Briane) on Wednesday, January 02, 2002 - 09:40 am: If you run Fire/Ice (and I think you should), you may want to run enough blue mana to use the Ice half of the card. It'll hold off high toughness creatures and draw you a card. Note that it works well with Smoke, as well.
Of course, if you run Ensnaring Bridge, that won't really matter much.
The only problems I see are against decks that don't use/need creatures to win. Against a Trix deck, you lose; put 4 Pyroblasts in the side, if not more blue hosing than that. Against a Sligh deck, you could lose; a smart player will limit the number of creatures they put into play. I also think your burn is slightly suboptimal, so I would anticipate their better burn to win the game. You'll also have a problem with white decks, so run 4 Anarchies in your SB.
The reason cards like Shock are good is because they can hit either a creature *or* a player. This may seem fairly obvious, but I can easily see this deck getting the opponent low on life and not being able to cement the win because all you are holding is creature-only burn.
You may want some sort of strategy to make the opponent play out their hand. If you're holding a fistful of creature-burn, a smart player won't play their creatures. You may want to play with some Vise-like effect, or an alternate win condition like Howling Mine (in the hopes of decking a non-creature deck).
I doubt all of these thoughts apply to your deck, but hopefully you'll understand what I'm at least getting at.

There are just not enough creatures in Oath, plus one of them is going to be a Morphling against which you are going to give major card advantage to them if you want to try and respond to the untargetable ability. And obviously, Crystalline Sliver by itself can completely shut your creature removal. Chill is also going to really hurt this deck after sideboarding. I think that you should add maybe 2 or three Earthquakes, as they will be taking a LOT more damage than you are. An Earthquake for three will do 12 damage to them if they have out three creatures, and you have a Repercussion out.
By Sephiroth on Tuesday, January 08, 2002 - 02:19 pm: Also, taking out 4 Inflame, 3 Thunderclap for 4 Cursed Scroll, 3 Fire/Ice could probably help the deck out a lot. Spashing Blue with only 4 Volcanics, 2 Shivan Reef would not make you at all vulnerable to Back to Basics or Ruination, and good players would'nt even side them in.

Thanks for your suggestions here is version 2.0.
Putting power surge in main deck puts in the vise like effect that Sephiroth suggested and forces players to play out there cards (hopefully creatures) and sort of wrecks blue counter spell strategy.
Making all my cards playable(not needing targets) allows me to play with power surge safely. Sideboard also has been modified to as better take on wider range of decks types.
Always look forward to your comments,
Old White Knight
