I think his deck looks like a fun new twist on slivers, but I have a problem with Sage's Dousing . your only wirads are the Mistform Ultimus s and a three mana counterpless thats not hard is very bad. I'd trade it out for Dissolve or Mana Leak , or even Spell Snare depending on your playgroup. Other that that, this is great!

p.s I'd consider putting in the: Xenograft , Shadow Sliver Runed Stalactite , Hive Stirrings , and Amoeboid Changeling . But you have to remember: you want thins to be every creature type to becomes slivers. May I also recomend Mutavault for those who have limitless money? if you branch off into merfolk/cleric spells, your deck will have an identity crisis. give some beatstick Runed Stalactite and watch him gain gouble strike and shadow for the win!

At first I thought about the Shadow Sliver , but my point was that creatures with shadow can't block creatures without shadow. Guess I'll keep it at least on the sideboard. I was also thinking about Dissolve . Thanks for the tips!

I feel like Mistform Ultimus will oftern underperform in the deck. I play a pauper GW sliver deck online, and Sidewinder Sliver performs really well in that deck. Might be worth a look.

Also, what does Xenograft do for you at this point? (Also I forgot to mention Adaptive Automaton is cool, never thought of it. I guess there are four Muscle Sliver s)

@CogMonocle yeah, Xenograft looks kinda out of place now. I think I'll move it back to the maybeboard.

Don't know why running a changeling is better than running another sliver in any of these circumstances.

@DavidBray Some reasons: 1. I want a blue/white deck; 2. I have all the listed changelings, so it would be way cheaper; 3. I was constructing a changeling deck and wanted to test it with slivers.

what about Galerider Sliver ?

@JamesERutledge you mean put more of it? The deck already has 2.

Why Mistform Ultimus ? Metallic Sliver gets all the sliver benefits but is much cheaper.

@Saljen Metallic Sliver is illegal in Modern.

no no, my eyes are just broken...looks good to me!

I like our other deck better... just because it's more unique, I commented on it. but I think they are both good.
