Counter Seal

This is a fuinjutsu developed by Tentei Uzumaki. This seal, when in contact with another seal, is able to transfer whatever the other seal contains into itself. The drawback is that the Counter Seal must be in direct contact with the seal it's stealing from. Also, the seal isn't powerful enough to transfer and contain something on the caliber of a Tailed Beast, but it would be able to take some of it's chakra.
