The problem here is that neither planeswalker would make it into a draft deck, let alone standard.
but the +4 is REALLY BAD in a control deck
So 8 mana target opponent draws 3-4 cards is not good.
Then, you get a -4 that is usually not relevant
The -8 is fine, but to keep dovin alive you give your opponent a reload, so it doesn't really do anything better than a normal wrath.
Finally, the ult is completely irrelevant. Make it "You win the game" or something.
They see some play, but not much, and this is no Nicol Bolas, Planeswalker.
