Ok... the dragon has prepared a contingency exactly against the tactic I'm suggesting, which could be called metagaming. But since TS is possibly the most broken spell in existance save Harm, it could also be called fairly reasonable. So, the cleric opens with a Quickened Haste (from a scroll; he's got the Magic and Trickery domains). Standard action, M's Disjunction. No more contingencies. Extra partial action, Time Stop. Third and subsequent actions, a dozen Harms (to make sure one will beat SR) and something to do damage. This tactic defeats any contingency, unless the dragon sets a contingency against Haste or Disjunction - which would be 100% metagaming, no excuses here.Actually with a contingency the Dragon can use a greater dispelling geared against the time stop caster or just use the contingency-teleport chain.
What I would do, is talk with the DM for a couple of days about this tactic and how I'm going to use it against the dragon.
Then, I'd show up with a wizard, Telekinesis, and a carriage full of crossbow bolts (GMWed to +5 via wand of course - we don't want DR to get in the way, do we?). At 18th, I can throw 4500 of them, and 1 on 20 will even hit, dealing enough damage to blow up the Death Star.
