This is all over the place. You're playing 19 creatures with 10 of them being singleton. A key part of magic is reducing inconsistencies in your draws. If a card is good enough to play, in most cases it's good enough to play four of. Minimizing deck size is important with this too. If you can play 10 unique non-land cards in a 60 card deck, that reduces variance significantly.
Now for your design. Is there a card interaction that you are interested in? You've got a bunch of deathtouch creatures that are mostly irrelevant, and some life gain, mostly at high mana. Vampire Nighthawk is probably the best card listed here, as it plays well on both offense and defense. As a flier, 3 toughness lets it survive combat with most things.
If you want to play with lifegain and deathtouch, you might look at a deck based on the following:
