Might want to edit this down to 60 cards

The deck is mono white, the theme is standard Angels. So i'm improving his theme by adding another color. Not to mention the first comment suggested adding black for demons.
For Burn spells I suggest "mizzium mortars" "Searing spear" "Bonfire of the damned" "Boros Charm".Your duals for red / white are "Sacred Foundry" and "Clifftop Retreat"
Guardian of the Gateless, Emancipation angel and codex are straight up bad and should be removed. Many of your other angels are questionable or should be less in number. Glaring spotlight is really a sideboard card, and not mainboard. If you want an instant to protect your creatures from spells then "Rootborn Defenses" is better.I also suggest you add red to the angel deck, that will give you access to burn spells to protect you in the early stages of the game. It also gives you access to "Firemane Avenger" "Gisels, Blade of Goldknight" and "Aurelia, the warleader" for angels. Also if you are in red you can use Boros charm for indestructibility to protect from removal among its other uses. You also need some sort of ramp ability, so Boros Keyrune would help a bit and maybe Chromatic Lantern. Also check out "Defy Death" to get your angels from the graveyard back into play with two 1/1 counters on them.
This deck is just baaaaaaaddddd......
I can tell you from expeience as someone who plays vampires in local standard tourney's that this won't work. Curse of bloodletting / Sorin cost too much, you need to have your oppent dead or close to dead by turn 5 when those could be played. You dont have cheap sorcery or instants to make great use of increasing ambition. Curse of stalked prey is nice, but I find that people tend to drop early blockers which will cancel your vamos before they can gain conters on them. Especially things like blade splicers are peticularly annoying. So I would add in Nightbird Clutches to gurantee damage and counter gain. You could also use Traitorous Bloods so at turn 4 and 5 when they drop that beefy creature to stop you you can take it from them and finish the game.
