Karn-Revisions

I went poking about the Commander and Competitive Commander forums at Reddit and didn't find much. This was a bit disappointing because the hive mind is usually a great source of ideas! Alas, this time it's looking like I have to grind things out myself.

So I organized the deck into lands, artifacts, creatures and All Is Dust.

After some review there are cards that I should pull:

Lumengrid Gargoyle: Too expensive for the payoff.
Myr Moonvessel: belongs in a combo deck
Myr Landshaper: also belongs in a combo deck
Omega Myr: no real payoff
Liquimetal Coating: doesn't do much else with the deck.
Welding Jar: belongs in a different deck. Commander has too much variance to get this to matter.
Rusted Relic: why play a vanilla 5/5?
Gemstone Caverns: Isn't awesome here.

Possible cuts:
Puppet Strings: doesn't do enough in multiplayer
Lightning Greaves: just not sure it does enough

Replacements:
Hedron Archive: mana + card draw is good.
Unwinding Clock: let's reuse my stuff.
Scour from Existence: removal isn't bad.
Endbringer: it's multifunctional
Kozilek, the Great Distortion: where else would this go? The card is pretty much terrible. But a 12/12 with Menace that can potentially draw me cards isn't bad. The countermagic ability is meaningless.
Bane of Bala Ged: removal isn't bad
It That Betrays: scary removal isn't bad
Ulamog, the Ceaseless Hunger: he's a dick.
Ruins of Oran-Rief: useful for every creature in this deck.

What I like about this selection is that it increases my creature count, which doesn't suck, boosts the mana possibilities, which doesn't suck, and has more removal possibilities, which doesn't suck.

So...I've basically spent time reducing the suck. I didn't want to remove weirdo cards like Yotian Soldier, Rocket Launcher, or even Phyrexian Processor. But there was enough chaff and solid replacements that I think I'm headed in the right direction.

Now that I've put in Unwinding Clock, however, Puppet Strings and Liquimetal Coating have more value. Liquimetal Coating turning a land into an artifact that I can destroy via Karn for one mana every turn is a pretty good deal. Puppet Strings to turn off the best creature every round is a pretty good deal.

So I'll be keeping them in the "maybe" pile. There are bound to be more cards that need to be cut as playtesting might show, and the ability to destroy lands like Maze of Ith or Urborg, Tomb of Yawgmoth can't be overlooked.
