Sorry for being rude, but this doesn't look like an actual deck. It's more of a pile of cards
Why do you play so many 1-offs? Basically I can ask you for every single card in the deck (except
Typhoid Rats), why you don't play this card four times.
If I were you I would sort out the deck a bit and play the important cards 4 times, this way you can organize your pile of cards to be a deck
.
One thing to cut out would be the rather bad removals for 3 Mana with sometimes hard constraints ("destroy target tapped creature") and put in some good CC2-Removal such as
Go for the Throat,
Doom Blade,
Victim of Night,
Terror,
Grasp of Darkness etc..
Also not good is playing some creatures with and some without deathtouch and then putting in spells to give deathtouch to creatures. If you have a deathtouch creature and one of these spells on your hand, it's just a
dead card. And giving creatures deathtouch doesn't even make so much sense for most creatures you have, since they do not benefit specially from it (instead you could draw a removal and kill with this).
I would either
play just deathtouchers and then something nice to ping creatures to death (such as the suggested
Viridian Longbow,
Thornbite Staff etc.), or maybe give them first strike etc.
or
play creautures who can ping like this (avaiable in red for example, such as
Cunning Sparkmage,
Fireslinger,
Goblin Sharpshooter and many more), have firststrike or something else that's nice and then give them deathtouch.
So I hope you can improve your deck a bit with these tips (I guess I made clear, that I see quite some space for improvement
), the
Viridian Longbow Combo for example is pretty fun^^
