Dream Cast

There's so little deck depletion that I don't see it really bothering anyone who's played more than 5 games or so. Unless you are likely to wipe out their entire deck, then it's just a minor annoyance to put your cards in the graveyard every now and again. And some graveyard decks would thank you for putting a few of their cards in the graveyard.
You do have quite a bit of defensive creatures, but your offensive creatures are easy targets. Usually, you would make a balance between offence and defence with only a bit of a trend towards either offence or defence, since a good offence is a defence in itself.
Even if you can hold them off for a while, you're not really going anywhere. If you are going for defensive, then you need a good late-game combo or game-ending creatures, because they are always stronger than a bunch of small weaklings (unless that's your combo).
Your lack of focus means that it will take you a long time to actually win by one of the 2 other possibilities. If you have a Glistener Elf out, for instance, you will take 10 turns to actually kill them. They would have no worries letting you put a few poison counters on them, since you are defensive, while they build up an attacking force, or do whatever it is they are specifically trying to do.

You really can't count on getting 2 cards that work together really well if you only have 1 or 2 of each card.

With 79 cards in your deck you can't really count on getting any of your cards, you can't count on your deck to do anything in particular, with the possible exception of getting at least 1 defending creature out in most games.

everything multihunter said is true. but don't let it get you down. the approach you took was correct. you came up with a theme/concept for a strategy for a deck and you attempted to build around it. albeit this isn't what would be considered a "good" deck, your rationalizing and logic all made sense. the number one thing you want is consistency. 4 and 3 of most cards that impact the game the greatest and most easily in your favor. a deck focus's winning in one major way,with most decks having an "alternative win condition" if their primary strategy fails. one way this deck could work,is if you made it a proliferating deck with poison/mill cards. cards like Grindclock, Decimator Web to name a couple. then throw some contagion clasps,and maybe some viral drakes. take out most the non infect creatures unless they serve a greater purpose i.e. overgrown embattlement; it helps ramp your mana and it can be a blocker. a deck usually basically does one thing; here it is proliferate, with which you can proliferate poison/mill kind of fitting your original idea of killing them by making them focus on defending them selves from one or the other. keep at it,creativity is the greatest tool.practice makes perfect =]

thanks that helps a whole lot!!! i just recently got into magic and dont have that many cards to work with but i will be sure to go to my local comic shop and hunt down some of those cards, and trim out what cards i dont need. thanks again your comments are very helpful!
