Plus if he is blindfolded he is going to have a hard time actually picking the right square that he thinks the target is in before he even gets a chance at hitting anyone; perception vs stealth.If you want to avoid any houserules at all:
The guy is blindfolded (cannot teleport, -5 to attacks, yields combat advantage) and restrained (-2 to attacks, cannot move or be moved, yields combat advantage). And there are guards. -sure- he can try to escape and start blasting through the walls, but it would likely end up with him dead.
Or he's in a solid box, with airholes at the top but no LoS or LoE outwards. 4e doesn't give hard and fast rules for breaking stuff, so it's entirely reasonable to rule that he can't blast through the stone walls or door with Eldritch blast -- he's stuck until someone can get him out.
With houserules, it's even easier -- add a martial practice that takes 10 minutes and lets someone bind a helpless target such that they cannot use powers. He's tied up with someone with that practice. Done.
Or rule that while there are no somatic, etc components, that it's entirely possible to tie someone up such that they cannot cast spells, just as you can tie someone up such that they cannot effectively punch someone; it just requires a helpless target and some time--that's not a houserule, just a reasonable GM ruling.
But I think it's far less complicated than that: 'You are tightly bound, you feel a cold that seeps from the shackles throughout your body draining your arcane reserves and leaving a buzzing in your head that makes concentration impossible. Until you escape from these bonds you are unable to cast any spells.' Set your conditions necessary for escape and be done with it. I don't think that is a house rule.
