The Hero card from Journey to Nix, The Savant, reads: "Exile {this}: Tap all creatures your opponents control. Those creatures don't untap during their controllers' next untap steps."
Say a player actives The Savant, and in response the opponents use various means to tap some of their creatures, but not all. But the end result is that all of the opponents' creatures become tapped. My question is, will all the creatures remain tapped during their controllers' next untap, or only the creatures specifically tapped by The Savant?
Yes, all will remain tapped. 'Those' creatures means all your opponents' creatures, otherwise the card would say 'creatures tapped this way do not untap...'
