Hi, I am going to be blunt, so I apologize in advance. Your list is pretty bad for today's meta for a few reasons. Supression Field and Damping Matrix are not very good; almost all relevent creature abilities are triggered or static. They stop Welder, Trike, non-sliver Flash, and seldom seen cards (Top, Slaver) or cards that do not matter to you (Tormod's, new faerie from Shadowmoor). Only about half of Stax lists today run welder, the rest are Mono-Brown, regardless, Jugg to the face laughs at Matrix/Field. Flash will kill you in response to Field or Chain it before going off. They do not effect GAT, Oath, any form of storm, or Ichorid at all. You are running 7 cards main that will be useful a very small percent of the time.
Stonecloaker is awful. Most prevelant decks will bounce your Angel anyway; you are doing their job for them. Disenchant is not as good as it used to be. It should not be maindecked, and there are better options for the Side. Land Tax does nothing unless your opponent is ahead of you, and even then is only effective when planning to Armageddon. Armageddon is, as you said, too slow. If it would matter to the opponent, it would be countered anyway (you have no way to protect it).
Exalted Angel has (in my opinion) been improved;
http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=143730. The Angel's lifegain is alot of the times irrelevant. Hoofprints is harder to remove, and churns out a token every 4 turns. Aven Mindcensor MUST be main. There are too many scrolls out there to leave it in the side. It's also nice to fizzle a fetch every now and again.
I would say the closest thing to what you want would be some type of GW Fish. Example:
Creatures4 Gaddock Teeg
4 Samurai of the Pale Curtain
3 Kataki, War's Wage
4 Tarmogoyf
4 Aven Mindcensor
4 Glowrider
Spells4 Swords to Plowshares
4 Thorn of Amethyst
4 Skullclamp
2 Hoofprints of the Stag
1 Balance
1 Black Lotus
1 Lotus Petal
1 Mox Pearl
1 Mox Emerald
Lands1 Strip Mine
4 Wasteland
4 Windswept Heath
4 Savannah
2 Flooded Strand
2 Plains
1 Forest
A list very similar to this just made top 4;

EDIT: Forgot to say, Gaddock Teeg is awesome. He cuts off such a large number of cards, it's amazing. No more Force, MisD, Gush, Chalice, Explosives, Tendrils, Gifts, FoF; the list just keeps going.
