I know it says can spend clicks to break subroutine, but it is causing a debate. The Corp player thinks you can't use a Decoder to just break the subroutines and that the only way past the Ice is to use the clicks on the Viktor card. I have Yog.0 Decoder

Viktor is a strength 3 code gate.

Yog.0 is strength 3 and breaks code gate subroutines

All requirements to break the routines are met. Yog.0 breaks through Viktor 1.0 for zero credits.
