Baldur's Swarm 2 (EDH / Commander) [Revision 1]

Wanted to get a feel of Alien : Resurrection.

"In hidden corridors, deep underground, slivers managed to escape from Rukarumel's laboratory and are now spreading in the sewers. The great Guilds try to hunt and contain the swarm while Ruka and her assistant find a way to end it once and for all.
But after all those experiments, maybe the Hive's spirit has taken over Ruka's mind. Will she kill the slivers, or help them to get out of Baldur City ...? dramatic fucking noise."

Ok, I did what I could with my cards now. I play the gates because it's cheaper than other lands I can't buy and it leads to this fun story plot. Plus I got a bonus win condition with Maze's End, where the slivers escape in the wild and ultimately destroy the world. So mana base won't move that much.

Rukarumel will have some win combos with Realmbreaker, the Invasion Tree and The World Tree ( > claim slivers are praetor or gods and fill the battlefield with the whole deck at once), Intruder Alarm ( > infinite tokens+mana with one mana sliver, one haste, one random).
Maskwood Nexus does exactly what Ruka's supposed to do but it's easier to cast. Just in case.
Last potential 1 shot combo is with Spiteful Sliver, Blasphemous Act, plus other slivers to add damages.

Some creatures will change over time. I still wait to get Dregscape Sliver, Virulent Sliver, Sedge Sliver, and will take out Leeching Sliver, Frenetic Sliver, Crypt Sliver. Other champions will come later in this priority order : Sliver Legion mandatory and > for fun (or not) Sliver Overlord > Sliver Queen + Basal Sliver. A good Alien movie needs a Queen, but I'm broke now.
To make things more spicy, the Commander card can be blindly swapped between champs at the beginning of the game, so I'd like to keep the deck in an all-rounder style and not too focused on combo making.

Spells seem costy, this section probably need some adjustments, I plan to maybe remove some ramp spells to get more utility.
If anybody wants to contribute to this deck's improvement, go on and let me know !
