Flodes,

Hibernation Sliver is a deterrent. It boasts to my opponents that their removal is useless as a targeted "problem sliver" will simply show up again. The truth is i've never found myself wanting to use this ability simply because there are better alternatives in the deck in the form of Crystalline Sliver or a simple Counterspell. Additionally, I've owned Deadly Rollick since it was released because I absolutely love the art. It's evocative of the earlier days in magic when the art was dark, sinister, and seductive. Speaking of seductive - Judith is hot. The art absolutely speaks to me - and what it says I'm sure I can't say in public.

Side Rant - I took this deck to a tournament over the weekend. It was advertised as a Commander tournament with prizes and no restrictions outside of the standard Commander banlist. Additionally, once you used a deck you had to stick with it throughout the whole tournament. Unbeknownst to me, a herd of cEDH players showed up and were crushing tables on turns 2 to 3 with regular consistency - they assumed it was a cEDH tournament, according to on of my opponents. After having one very exciting game I realized that while this deck is decidedly not one of the archetypes, it could at least leave an impact on a cEDH game. So I think I want to squeeze in some more interaction just to ensure that this deck could at least consistently hang at a cEDH table. So, that's the other reason why I wanted to slot in Deadly Rollick. Also i'm trying to slot in a copy of Flusterstorm. It's a great spell and just got the foil old border treatment in MH3 as a buy a box promo. I'm trying to decide on what to slot it in for, but i'm having a tough time deciding on what to cut. Do you have any ideas Flodes?

That's the end of my long rant, thanks again for commenting.

Edit: Made a few changes due to bad grammar/spelling

Mortlocke and Flodes,

To jump in on this, I recently picked up the Flusterstorm you mentioned and have been trying to fit it into this list somewhere. Strix Serenade was also on my radar, as it rounds out Swan Song nicely. This is the primary deck I play, and the cards on the chopping block for me are Cyclonic Rift and Pact of Negation. Rift is underwhelming unless overloaded and the Pact upkeep cost (unless protecting your win on your turn) is basically a time walk. 5 or 6 open mana is coming close on win-con range, so it seems less than ideal to leave that open or spend it on upkeep. Choosing one I would probably replace Cyclonic Rift with Flusterstorm, but I may give the Serenade a chance as well.

Hi, how about playing Lands, like Path of Ancestry or Sliver Hive? You could as well play The First Sliver, with is also a great commander in my sliver deck. What I really like in 5Color Sliver Decks is Bring to Light, it will get you any Sliver you need, including the 5 Colored Sliver Legends or even removal or a Patriarch's Bidding.

LordDonato,

Cutting Cyclonic Rift or Pact of Negation are bold suggestions that i'd find myself very much against. Sure Cyclonic Rift is expensive being a 7 CMC spell - but it's a one sided untargeted mass removal spell at instant speed - 7 CMC for that kind of effect feels like a bargain. Pact of Negation is great because I can bait out my opponent into casting a big spell once I am all...tapped out. Losing the game is almost irrelevant if I am popping off on my turn and am able to counter an opponent's attempt at interacting with one of my combo pieces. I will however revisit these thoughts and opinions if my meta changes or shifts toward cEDH.

Seuchenschutz,

Path of Ancestry has a solid effect - but the cost of entering tapped is far too high a price to even be considered. Sliver Hive was once in this deck many iterations ago. I chose to cut it however as the colored mana it provided was exclusive to creatures - which is a pretty big drawback. It's last ability is pretty much irrelevant, as I'm never going to spend 5 mana - and tapping a land to create a 1/1 creature token. If Sliver Hive didn't need to be tapped to activate it's second ability then it'd be auto include for sure, and probably way more expensive than roughly 20 USD. Bring to Light was also in this deck many iterations ago, and I see what you mean when it comes to paying WUBRG, tutoring and casting one of the legendary Slivers. I'll need to think more on this spell before giving it another run. Patriarch's Bidding was also in this deck many iterations ago, but more often than not I would find this spell backfiring on me massively as it also assists all of my opponents as well. It's a cool spell - but it can also enable my opponents to combo out before I do - or at the very least enable them to thwart my plans.

so a cut for Flusterstorm... Eladamri's Call or Nature's Claim would be my choices. You either have better tutors, or these effects on a Sliver.

Id also likely chuck an Aura Shards in if you want some more interaction which isnt mandatory. You can play creatures at instant speed, or poop out a sliver baby with Sliver Queen that voids your need for Nature's Claim.

Have recently removed Carpet of Flowers as well given large numbers of non typed lands producing what people need, and so the benefit is becoming less and less. Every set there seems to be a new cycle of lands which dilute this cards power.

Anyway, just my little input from my side of the hive. Hope you are all well. May the Queens blessing be upon you
