Careful Spell and Evard's Black Tentacles?

[werescythe]

to be clear, I do think the metamagic is a little overtuned if it works on every save for 1 SP. working on only the first saving throw against that spell would be a reasonable middle ground (or, alternately, making it cost a little bit more, though I'm not completely set on how high that cost should be; I'm torn between it working on one save/person for every SP you spend, or just a flat 3 SP for all saves against that spell, because I think 2 SP is still not quite enough).

Honestly, I'd be cool with that, if WotC came out with a new version of Careful Spell (or some other metamagic variant of it) that could keep the group safe from the spell for the full duration for 3 SP.

It would make it a very good option (compared to now).
