You run 4 Living Wish. If you're going off fully- which implies that your opponent doesn't have counters anyway- they certainly won't be able to stop all of them unless they're sititng on CB-Top at 2. In which case, again, why are you able to combo off at all. In that scenario you just try to use GSZ and dorks to beat down, hopefully getting a Kamahl into play. It's worth noting btw that GSZ is way better against CB-Top and Chalice than Pact would.

I often cast a second Regal Force, but that's 1 from a Wish and 1 main.

If I understand the VV plan correctly, there's no Buried Alive involved. It's just a card that happens to be good against a lot of strategies that beat the deck naturally.
