Arbor elf is also nice if you have those enchantments that when you tap enchanted land for mana, you add an additional of any color to your mana pool. Then, you can tap arbor elf, untap the land, and get two more mana, rather than just one.

You know, Rite of Replication could be very helpful. If you have master biomancer in play, it's another way to win, especially if you use Rite of Replication on master biomancer. =D

I wouldn't use hindervines. If a deck has any +1/+1 counters in it, it kinda ruins that card.

a friend of mine made a deck like this once. it was super kool, but never fast enough.

It would be a scary deck in multi-player. Everyone is decking each other out, then suddenly, they realize you're still there. 0.o Or if they're just sitting around waiting for someone else to make the first move (like my boring friends do :P) then suddenly BAM they don't get much of a reactionary move. :D
I'm not that familiar w/ artifacts, so i can't rly help you much with getting similar but cheaper cards, sorry. I've never rly made a good artifact deck. I've attempted, but never come close to a good one. I always end up disassembling them.

Vampire Nocturnus could help the deck a bit. I think it goes great in vampire decks.
here's my vampire deck if you wanna take a look (it's prob not as good as yours, but i like it) =D

Narrow down your deck to 60 cards.
Playtest your deck (meaning, just play w/ friends) and if you notice that when you draw certain cards, they don't usually help you win, take it out of the deck. That way, you only have the best cards in your deck and you're more likely to draw the cards you need to win.
I'd probably only have 22-23 mountains (depending on the mana curve.) I can't rly tell you how many until it's narrowed down to approx 60 cards.

If you wouldn't mind going to my page and looking at some of my decks and giving feedback, I'd appreciate it =D

This is a prette sweet deck. But it seems it would do poorly vs any aggro deck.

Maybe the ordeals. you only have 2 of them. oh weird. my computer sometimes accidentally deletes sentences. I think that last post of mine was if you give him +1/+1 counters and Kalonian hydra. :P idk something like that.

I'd put in Master Biomancer. It's so good. And if you use Give on him + Kalonian Hydra, your cards will get super strong super fast.

ok. kool kool :P wasn't sure if there was some hidden super op combo i was oblivious to. lol

Not to sound slow, but i don't get the deck. Could you explain it? :P

You could put in crumbling necropolis. That way you have a way of casting both breaking and entering.

I'd take out Travel Preparations because it's not a single target and replace it with Hunger of the Howlpack

I wouldn't put in Nylea's Presence. Anything with any type of basic land walk will destroy you. Maybe put in the card (Can't remember the name) where you tap and add mana equal to your devotion to green.

=D i love decks that are banned in every format! =D

I've been looking for those names. I'm making a custom set thing for fun with a magic card creator. It's a wedge set. :P (i also have a League of Legends set) XP

Hm... i think you need more legendaries... not enough :P maybe Avacyn, but that might be too expensive.

Take out Sliver construct. it really isn't good.

ok, that's not the way i understood it. It sounded to me, when i read the rules, that creatures cannot tap to attack or tap as COSTS for spells/abilities (ability costs come before the : in the text. I.E. G:do stuff. or T: do stuff. or Tap a creature you control: do stuff) while the creature has summoning sickness. however, a spell or ability that forces a creature to tap (like twiddle) can still make it tap.
