What part of divine favor is good design?
It actively rewards bad play.
actually i was disagreeing with both your statements, freeze mage is uninteractive, aggro paladin isn't uninteractive and with the amount of cards in the game that can answer your board state it isn't exactly brainless to play either.
as for divine favor (another point of interactivity for aggro paladin, maybe you should keep it in mind when you consider your plays), there are tons of cards that can be as or more disgusting than divine favor, a number of them were printed this set.
