yes, it's a 1.27 update
and it's actually better than spine against some gods
Too right! It's certainly a vast improvement on fire buckler now, since it's cheaper, prevents damage, and deals with such pains in the arse as Forest Spectre and Lava Destroyer. It's too bad that when Skull Shield kills an immortal creature that the skeleton becomes immortal also. This would have given my deck a useful out against Divine Glory. (I suspect, tho, that Sanctuary might eventually be more important to that matchup).
Also, I'm quite excited about the new skeletons which mutate when rewinded (as I'm sure is everyone!). Most False Gods play limited colors, and therefore can't make use of many of the random creatures that you would give them. A rainbow deck like this can, however, by rewinding and mindgating them. (Aside: Rainbow decks with Eternity and Boneyard just got a hell of a lot better, didn't they?)
So, now, not only am I playing with all of my opponent's cards, I'm playing with a bunch of random creatures as well. This deck just gets more and more fun

Too cool. I'm back to playing a 33 card version of the deck again, without Electrum Hourglass, and without Aflatoxin, and with one PA (to give the deck an out against some of the harder FGs). The win % has probably dropped a couple of percent, but it's much more fun to play. Aflatoxin, especially, rewards dull play.
I'm off to donate. I should have done it months ago.
