Let's have a look at your land base first. I take it that you are making a standard deck for FNM? If so, you should have 24 lands minimum. You have an average mana curve of about (3) so that means you'll need 24 lands, minimum. If you were making a mono-red deck, you could get away with using 20-24 lands because mana costs are generally low, requiring the deck to be fast. I have noticed that you have a lot of tapped lands, personally, I have found that having tapped lands makes your playing slower. You could use lands like
Prairie Stream if you have 2 basic lands in play, it won't enter tapped. You could also use pain lands such as Caves of Kolios which enters without tapping, they produce colourless mana, but if you pay one life you can add either black or white mana.
Your deck does not seem to have a very coherent structure. Apart from wanting a vampire enchantment deck, which is brave btw, you are utilising very random singular cards that do not have a great synergy. You should
simplify your deck by removing cards that do not work well. I will give you an example.
Kalastria Healer and
Drana's Emissary work well because they trigger the 'ally' mechanic "When an ally enters, your opponent loses 1 life and you gain 1 life." having 4, instead of 1, means you are more likely to draw that card.
You also need to have a
balance between the number of spells and creatures. having more spells/creatures depends on the deck you are using. 18 creatures/18 spells = balanced. You can change this to include more spells, especially since you are using enchantments. You will need cards that prevent your cards from being 'removed' by spells like
Flaying Tendrils or
Languish or
Eldrazi Displacer, which will cause your auras to dropped off as the card is exiled. Including cards like
Negate works well against those spells, because they are cheap, and work against Planeswalkers.
Try cutting down on the amount of colours you are splashing, to keep it
simple, or you might find you are not pulling the correct mana combinations to win. I hope this helps you. If you would like more advice, please let me know.
