If I have Vildin-Pack Alpha and Arcane Adaption, would Nicol Bolas, the Ravager transform?
Yes, this works but won't give you the result you're looking for.Nicol Bolas will enter the battlefield as a Werewolf and trigger Vildin-Pack Alpha's ability. When that trigger resolves, you can choose to transform Bolas, but if you do Bolas will be a planeswalker with no loyalty counters and will go to your graveyard before you can do anything about it. Planeswalkers get their starting loyalty counters from a replacement effect as they enter the battlefield, and since Bolas didn't enter the battlefield as a planeswalker, he doesn't get those counters. This is why all the double-faced planeswalkers that start as creatures exile themselves and return to the battlefield transformed.
