Chronosavant skip turn and werewolf card spells cast?

[Mint]

Its other player's turn and he uses Chronosavant

now its my turn and I cast more then two spells during my turn

now its other player's turn which he skips

now its my turn again

would my Wildblood Pack transform back to Instigator Gang?

[Arix]

Yes. A skipped turn doesn't begin and then immediately end - it just never happens. It goes from your turn straight to your turn again, and since you cast two spells last turn, the transform ability on your Werewolf will trigger.

how about after game is restarted due to Karn Liberated?

[Arix]

The restarted game, for most intents and purposes, never happened. If Karn exiles a Werewolf, then you'll bring in the non-transformed side. Since there was no "last turn" to look back to, the ability doesn't trigger.
