I definitely vote for Eternity plus Enchant/Protect Artifact. Also, it seems a waste of a Time deck not to put in at least a couple of Hourglasses.
You won't get my vote. Mark of time is not enough to pay for Hourglasses let alone Eternity. You need Towers to pay for those which would chance this whole deck.
I would probably drop 2 Quicksand and take 2 Shriekers to get more damage. No 30 card deck needs 6 Quicksand.
Tried to switch 1 quicksand and 1 rewind with 2 shrieks: it works greatly! Nice idea
