That's right. More Innistrad, though this time we're looking at an aristocratic wedding. Lots of more direct upgrades this time.

White:

Starting off with a change that heralds a few of the focuses in this update, we're swapping Wings of the Guard (typically a 2/2 on the attack, though it can get up to 4/4) for Barbed Spike (a 2/1 all the time). In addition to this being an average upside in stats (at least, while not attacking), Spike also has the advantage of being an artifact (two atifacts even) and leaving behind a goodie when it dies.

The other white swap is a little closer. The ambush potential of Devouring Light is being swapped for the unrestricted targetability of Declaration in Stone.

Blue:

A blue defensive one drop swap! The second of the cheap artifacts added this go around, Hard Evidence should help Tinker and spellslinger lists. Vortex Elemental isn't a bad card, but Hard Evidence does most of what it does and also can cantrip, so the Elemental leaves for now.

Given the heavy reliance on basic lands in this cube, Thirst for Discovery is just Compulsive Research but instant speed. So it has been upgraded.

Black:

Voldaren Bloodcaster is yet another cheap artifact producer, but this time it's an Aristocrat. It also has a solid base rate of a 2/1 flyer that leaves behind a treat when it dies. The swap for this one is a card that isn't at its best in any deck bar two, and the Worldknit deck doesn't need the help from Corrupt to be good. Mono-black will be ok with a more efficient beater rather than the big kill spell.

Altar's Reap > Village Rites is another direct upgrade, albeit one I'm sad about. I've held off till now because the Altar's Reap art is lovely in foil, but needs must.

While going from an exile effect to a destroy effect does mean black has less ways to deal with indestructible threats, black has many ways to deal with those already (Extinction Event, Tragic Slip, etc...) and Gild is less versatile than Damn excepting that.

Red:

Poor Skin Invasion. It always seems that a 1 mana 3/4 would be a good rate, but actually getting it active is trickier than one would think. So out it comes, replaced with another 1 mana creature that comes with an artifact stapled to it in Voldaren Epicure.

Green:

Mana dorks are good, exalted is good, mana dorks with exalted are amazing. It's even a Goblin for those incidental synergies. Sorry mono-green permanent removal fans, Beast Within is going beast with-out.

Multicolor:

Yet more Aristocrats support, we have Kardur, Doomscourge. The omni-goad on ETB is also quite nice in multiplayer. Carnival Hellsteed is the cut this time. Unfortunately the Nightmare Horse doesn't end up finding its way into many decks.
