Cool list so far!

Here are a couple card suggestions/easy upgrades:

Commander's Sphere & Darksteel Ingot replace the lockets for them :)

Negate & Counterspell are cheap counters and I'm sure you'll enjoy them. Replace disdainful stroke.

Swiftfoot Boots Make Jeleva hexproof and haste, you want to make sure she attacks and no one bounces her away.

First thing I would personally invest in after those cards is a manabase that doesn't come in tap as much.

You have a goods amount of draw and killer spells.

I hope this helps!

Thanks, those are some really helpful suggestions. I had the lockets because I used to have a lot less carddraw, but you're right, Commander's Sphere and Darksteel Ingot make a lot more sense right now. I just bought both of them a couple of days ago so it's an easy switch :)

How many counterspells do you think would make sense to run in a deck like this? Is 1 fine, considering you can often copy an opponents counterspell if they try to counter you, with spells such as Reverberate?

I did use to have Swiftfoot Boots in my deck, but I took it out for Lightning Greaves. Would it be better to run both for the consistency? I only have 3-4 other creatures worth removing, and my playgroup play very little spot removal

I'm working on slowly adding some better lands, mostly the cheaper shock lands and check lands for now. A work in progress, you could say

Again, thanks a lot for your help, I very much appreciate it (:

This actually looks pretty fun! One card I think would be awesome in here is Mirage Mirror. You would be able to copy an opponent's enchantment that would benifit you somehow or copy a creature for a big blocker/attacker or for it's great trigger or whatever man! This card is becoming a staple in all my edh decks.. It's just so versatile.

Ah, that's not a bad suggestion! I guess that in worst case you can always copy a Gilded Lotus or Thran Dynamo for that 1 extra mana. At 0.3 euro's I'll just buy one and try to see what I can cut for it. Probably Worst Fears

Thanks a lot ^^

Here are some cards for the budget, since you are trying to cut down on some cards and add in more interaction.

Card Draw:

Mystic Remora

Dark Tutelage

Windfall

Notion Thief

Ramp:

Izzet Signet

Rakdos Signet

Talisman of Dominance

Talisman of Indulgence

Fellwar Stone

Chromatic Lantern

Instants:

Counterspell

Delay

Arcane Denial

Swan Song

Snap

Frantic Search

Hope that helps!

I have pretty similar deck and I have to say, one card I've had a lot of fun with is Cruel Entertainment, but my kicker is I always have to target myself. If my two opponents realize it's in both of their interests not to screw with each other, they wont, so I target myself so we can have a bit of fun. It felt bad casting Worst Fears off of Jeleva, but CE is super fun. Mind's Dilation is also a good one.
