As much as I want to avoid making that deck more annoying, a few protect artifacts would prevent a pulvy from taking away all of your per-turn healing. That way you face less mid-game losses due to being saved solely by miracles.
On another note, with a bit of trimming, this might make a great arena farming deck. If you manage to deck out some gold/plat decks at 499 HP, think of the incredible money gains. On the other hand, it might take too long to even be worth it. I guess it's up to someone with the time to test. :p
