This one won't be an option for some people, but if you replace the nymphs and use more copies of pandemonium, antimatter, shards, etc, it will probably do well enough. I used what I had, but modify it to fit what you've got.

Diamond Shield shuts down much of Ferox's offense, and a lone purple nymph completely wrecks his day. Sit on your bum until you have 500 hp. Make the kill with deckout or void shards. You can antimatter your own creatures with a nymph to prevent kills before you have max hp. Don't worry about the jade staff wrecking your EM; just save a stoneskin or shard of divinity to heal yourself on the turn you make the kill.
edit: blanks are shards of the void, 3 unupped 3 upped; like I said, I used what I had :p
