Dragon vs. Wizard

[Renegade Paladin]

The dragon wins because it has excellent saves, more hit points than God, spell resistance, spellcasting as a sorcerer, the fastest natural fly speed in the game, equipment that it would be stupid not to use, an INT score high enough to ensure that it isn't stupid, an impressive array of natural and supernatural attacks, and is too big to fit in a forcecage. And even if it was, it could in all likelihood disintegrate the blasted thing anyway. If dragons of equal CR aren't the toughest things your party ever has to fight without resorting to creatures of a higher challenge rating than the average party level, then you're doing it wrong.
