Dweller + Pact

[HandsomeStallion]

When you enchant {unhallowed pact} to your {treacherous pit dweller}. What ends up happening? Would the dweller bite you in the face regardless or is he friendly.

[Poof]

Even undying brings back the creature under your control then the game sees it entered the battlefield from the graveyard and your opponent gains control.

it bites you in the face. whether it undies or unhallowed pacts it came from the grave onto the battlefield. and therefore the switch triggers. you can stop this with {cloudhshift} though

[Sagemaster]

I believe he can choose to bring it back without undying and thus keep it because of the pact

no because pit dweller doesn't trigger specificly to undying it triggers whenever he's reanimated. so if i {unburial rites} it it switches control
