Where do they even get 30 people who can cast 3rd-level spells? That's like an entire region's supply of 5th-level characters. Are they in Eberron and using mass-produced wands of counterspell? Maybe they're the entire high-threat response team of a major empire or planar metropolis.

I'm trying to game out how many of my characters it would take to rescue the player if that's really 30 5th+ level antimages, and with that many counterspells on the field I think the answer is that they could probably shut down every spellcaster I've ever played, at least for long enough to take out the primary target. The only D&D character I've played who really has a hope of accomplishing anything is a very high level 4th edition fighter, and even at near-epic levels things still look dicey because I bet those guys are all packing a bunch of other spells like hold person and only one of them has to hit to really mess up his day. Maybe if he teamed up with the high level half-celestial paladin of freedom from 3.5...

Actually I just remembered you have to see your target to counterspell them, so actually some people like the 3.x Sublime Chord would be in the clear as long as they cast improved invisibility while out of sight, but I'm betting the anti-mages are prepared for that too, somehow. It might even things up though!
