If my opponent has Winnie the Pooh – Hunny Wizard and Winnie the Pooh – Hunny Archmage in play and I choose one of them for One and Only, will the other be banished?
Yes. When the effect compares names, it only compares the larger name on the card, not the version. Both cards are named “Winnie the Pooh,” so when one of them is chosen, all other Winnie the Pooh characters are banished, regardless of their versions. Narrow Escape Narrow Escape
