Returning lands to hand is very powerful. It's almost as bad as land destruction, which is not liked very much. The "return spell" makes this a hard counterspell, which tend to be at least double-. That would be powerful by itself. Overall, I think this should be uncommon, cost at least , and not be a cantrip.

And then it'd pretty much be Venser, Shaper Savant.

Well, he's a legend, making it a bit painful to cast the second time (not much painful though)

But yeah - makes this nearly competitive with counterspell, and on top of that it's a boomerang? Ok, so it's a soft counter, and they'll cast it again next turn, but. at least, I'd think.

This is so much better than Repulse (and Regress for that matter), it's not even funny.

­Remand isn't despite being "hard", but give it all these other options and it clearly needs to cost a lot more.
