I play a Dimir deck often and I need to get rid of {Rest in Peace}, {Ground Seal}, and {Tormod's Crypt}. Are there any ways I can get rid of them without splashing white or green?
{Cyclonic Rift} and forcing them to discard after bouncing it back.
You could take the {Shimian Specter} {Reap Intellect} route too. Works with {Cyclonic Rift}
