If you can work with the Disney Channel West channel (doubtful but I never know), Ducktales is on from 6 PM PST (more or less right now upon posting) to 7 PM PST, the end time of which is the new time for MHA on CN East.
It looks like both are tied with 1 vote each. I'll be tiebreaker. "Phineas And Ferb: Christmas Vacation" moves to the next round. The next matchup is between The Loud House episode "11 Louds A Leapin" and the Sofia The First episode "The Mystic Isles: A Very Mystic Wassalia ".
