Intruder deck (UG) - Need some help with draw

[Nubi]

I've been working a bit with this deck idea, however I can't seem to find any decent draw spells for it. Also note that it must be kept very cheap (4 BoP would be sweet, however I cannot afford those currently - aka. I'm broke)
I'd like somewhere around 8 draw spells, and they need to be effecient as I cannot tutor up the Alarm (no enlightened tutor).
So here's the decklist, and I'll explain most of the card choices below it.

Combo (4):
4 Intruder Alarm

Creatures (14):
4 Shrieking Drake
4 Horseshoe Crab
4 Brass Man
2 Lowland Basilisk

Draw (?):

Ping ability (10):
3 Psionic Gift
3 Hermetic Study
2 Viridan Longbow

Mana (24):
4 Krosan Restorer
4 Quirion Elves
4 Yavimaya Coast
6 Forest
6 Island

[Shrieking Drake] - It's combo with Intruder Alarm + Elves / Restorer (it CAN bounce itself, right ?)

[Horseshoe Crab & Brass Man] - They can be untapped w/o casting creatures under the Intruder Alarm.

[Lowland Basilisk] - Creature control, enough said

[Ping ability stuff] - I've chosen to run only 6 enchantments and 2 equipments, due to the inherent card disadvantage of the enchantments, should the creature be killed.

The mana base I figure should be self explaining, however if someone knows something better than krosan restorer for providing blue mana (being a creature, that is somewhat cheap to cast, wirewood channeler is imo too expensive)

So I'm lacking Draw spells, and actually I'd like some room for some counter magic as well (Probably Mana Leaks) - Yet I don't know what to remove, maybe some of the ping enchantments, any ideas ?

[Nubi]

I've just thought about something: Genesis Chamber. It could rock with the drake even w/o infinite mana. However it could also hurt me too much too soon - any ideas about this one?

Genesis Chamber would be amazing.

I feel like a chode telling you this (because a friend of mine has a deck like this and it irritates the heck out of me). Instead of 3 Hermetic Study, 3 Psionic Gift, 2 Viridian Longbow, you might consider 4 Hermetic Study, 4 Sigil of Sleep. That would also allow you to drop 2 Lowland Basilisk, in favour of 2 Viridian Longbow. Trust me on this - A machine gun crab with Sigil of Sleep on it (despite being serious card disadvantage, if it dies) will keep your opponent's side of the table free of nuisances.

As far as card drawing goes, Curiosity suits this deck as well. Often, you end up putting all your eggs in one basket (Horseshoe Crab + Hermetic Study + Sigil of Sleep + Curiosity), but if you combo out fast enough, it isn't really an issue - especially in casual play. Also, instead of the Brass Men, you might consider just using Prodigal Sorceror or anything else that already has the ping ability. That way, you can get parts of the combo going without having to waste Hermetic Studies or worry about putting all of your creature enchantments on a single creature.

Lastly, Ophidian is often touted as a strong card drawing engine. I've found it suboptimal in casual play, since there's a much greater chance that it will be blocked (unless you already have the Sigil of Sleep deal going on, in which case you're 3/4 of the way toward winning, anyhow).

Well I already know about the power of Sigil of Sleep, as I have a deck using it  

However as you say I risk putting all my eggs on one creature, that's not a problem if I have some counter magic, however I don't :/

Also I was thinking about adding the cruel Apathy + Curiosity combo to it, although I don't know what to remove for it.

And lastly, I'm worried about trying to do too many things at once, any suggestion on that ?

Here's my revised decklist, whether it'll work I have yet to find out:

Combo (4):
4 Intruder Alarm

Creatures (15):
4 Shrieking Drake
4 Horseshoe Crab
3 Brass Man
4 Prodigal Sorceror

Draw (4):
4 Curiosity

Ping ability and stuff (13):
4 Psionic Gift/Hermetic Study
4 Sigil of Sleep
2 Viridan Longbow
3 Apathy

Mana (24):
4 Krosan Restorer
4 Quirion Elves
4 Yavimaya Coast
6 Forest
6 Island

Whoops almost forgot: Any ideas what to cut for Genesis Chamber ? (I've been thinking about Brass Man)

Edit:

After a bit of goldfishing I've changed it into this, the genesis chamber is really nice w/ drake. Also I found some cheaper alternatives to the restorer:

Harvester Druid
Urborg Elf
Utopia Tree

With the tree or the elf being the best (quite unsure whether I want the damage ability or the extra toughness, currently I go with the toughness)
The genesis chamber meant I removed Brass Man. Without further ado here is the current list:

// Creatures
4 Shrieking Drake
4 Horseshoe Crab
4 Prodigal Sorcerer
1 Rootwater Hunter - the original tim has most synergy cards in the deck (apathy, curi, sigil), thus I run an extra
3 Genesis Chamber
// Draw
4 Curiosity
// Other stuff
4 Intruder Alarm
4 Psionic Gift
4 Sigil of Sleep
4 Apathy
// Mana
4 Utopia Tree
4 Quirion Elves
4 Yavimaya Coast
2 City of Brass
5 Forest
5 Island

Still BoP would be better than the quirion elves, however it often goldfishes turn 5 as it is now (usually w/ tim + curi + apathy)

EDIT: New decklist

I've been thinking abit about it, and the tims are usefull by themselves, whereas the crab sucks w/ ping, so I switched the 4 crabs for 4 tims, and the 4 psionic gift for 4 pemmins aura:

// Creatures
4 Shrieking Drake
4 Zuran Spellcaster
4 Prodigal Sorcerer
2 Rootwater Hunter
2 Genesis Chamber

// Draw
4 Curiosity

// Other stuff
4 Intruder Alarm
4 Pemmin's Aura
4 Sigil of Sleep
4 Apathy

// Mana
4 Utopia Tree
4 Quirion Elves
4 Yavimaya Coast
2 City of Brass
5 Forest
5 Island

EDIT: Changed to mono U!!!

Having played the deck against admittedly a few decks (UGr madness, T2 affinity, Casual reanimate) I found out the green part of the deck sucked pretty hard, so I switched the green for 4 silver myr (does the same sweet thing with alarm + drake) and the result is this:

// Creatures
4 Shrieking Drake
4 Zuran Spellcaster
4 Prodigal Sorcerer
2 Genesis Chamber

// Draw
4 Curiosity
4 Impulse
4 Brainstorm

// Other stuff
4 Intruder Alarm
2 Charisma
4 Sigil of Sleep
4 Apathy

// Mana
4 Silver Myr
1 Sol Ring
15 Island


While the deck has somewhat few mana sources now, it has alot of library manipulation (impulse, brainstorm) to make up for it, still I'm probably going to add 2 more mana sources (an island and a lotus petal), yet I don't know what to remove for it.

Also I've been toying with the idea of cutting sigil of sleep for propaganda, and cutting something for furious assault (nice w/ drake, win w/ drake+alarm+myr)

I'm going to playtest it against FCG today, and maybe against some casual WW
