Slivers Casual/Multiplayer Highlander

[BradWayne]

I was in the process of building the best all slivers highlander deck EVER, (40 lands, 60 slivers, one of each) however my calculations were wrong, and there are 59 slivers (Coolstuffinc.com counted the sliver token card as a sliver) instead of 60. I don't want to run a 41st land (40 lands in 100 cards is equivilent to 24 lands in 60 cards, and the curve actually is pretty okay.) So I have room for ONE non sliver card. Any ideas? So far I've come up with these possibilities:

Slate of Ancestry
Proteus Machine
Coallation Victory
Karona, False God
Mistform Ultimus
Harsh Mercy
Patriarch's Bidding

but I'm sure ther's something better that I've missed. What would you run?

Also, if I play elder dragon highlander with it, I'm gonna hafta take out sliver overlord from the maindeck as well, which frees up a second spot! What would you run there?

Thanks for the ideas!

For the first case, Mistform Ultimus is the way to go.  After all, it IS a sliver.  If you have a second free slot, I think Patriarch's Bidding has a powerful case for it, likely giving all of your slivers a big boost from whichever ones you bring back.

Urza's Incubator
Soul Foundry (omg muscle sliver on soul Foundry = crazy)
Mistform Warchief (i think is better than ultimus)
Coat of Arms
Disenchant (Tempest: with the sliver picture)

[dandan]

Chromatic Star
or
Aether Vial
or
Mana Cyclix
or
Terrarion

Getting the right coloured mana is the be all and end all of your deck

While 1 of each sliver is pretty cool, wouldn't it probably work better if you could have some form of tutor engine because you need some slivers sooner than others, and some slivers are really not good.  The 5 worst probably being armour, venser, barber, plague, and basal (assuming that you are not running a heartstone to combo with queen).

I would cut those 5 and use these as my 6 open slots:
Demonic tutor
Vampiric Tutor
Wordly tutor
Imperial seal/Eladamri's Call (if you don't have a seal)
Patriarchs Bidding
Aether Vial

If overlord is cut for EDH Id go with Coat of Arms

EDH is a 100card format, the Overlord counts towards that.

And Mistform straight up blows.
