So, I thought I would give this deck a spin with the new London Mulligan rules and boy is it still bad. Fun though! I used this ancient thread to help guide me and here is what I can add to the next intrepid adventurer that falls into this trap.
Spoils of the Vault killed me twice in three rounds from 20 life looking for a 4-of. Ouch.
Rampage of the Clans is a option for the green decks. It destroys all enchantments and artifacts and gives the controller a 3/3 for each one destroyed. Not as deadly as Opalescence, but still very good.
Godspeed to anyone trying to weather this storm.
