o-ring (or recoil!) will make a passable replacement for vindicate.  You could possibly use kjeldoran outpost to replicate the functionality of elspeth, but that would make it even more important to get hallowed fountains, maybe.

The rest is fairly cheap... Oh, except crucible.  Darn it.

sorin, lord of innistrad could maybe replace elspeth
