Other Each Fight Classes Dragons and Dungeons The
Depends on the arena, and how much prep time they had for each other.
Level 20 characters with no advance warning on what they'd face, generic (If powerful) rather than foe specialized equipment, and a featureless arena that won't give advantage to high mobility/stealth: Moon Druid followed by barbarian would be my assumptions for first and second place.
With advance warning: Wizard, then Onion druid.
Here's how Wizard takes the field with advance warning. Readied Moonbeam set to go off just after the moon druid's turn, followed by power word kill. Unless exceptionally lucky or exceptionally healthy, the onion druid gets one chance to hit the wizard before being forced back into normal form and keeling over dead, or two if he wins initiative.
