I am using Tamiyo.
My opponent casted GR onto the battlefield.
I had Spires of Orazca on the field,
used Tami’s 2nd ability (Oboro Knowldge) to disable GR,
then attempted to cast Connive to steal GR.
This did not work.
I used this combo against several creatures that entered the field, but specifically, GR would not let me steal it.
I did not have a full hand. I played specifically with one creature in my deck so I could do some creature thieving for fun and profit. I was able to steal some other creature that was on the board after I bounced GR back to my opponent’s hand. GR came back to the board and I could not steal it… sad times.
I’ve had several issues with disable specifically from Tamiyo’s ability — like Swift Reckoning doesn’t work.
This should be looked at. It’s a pretty broad issue where it seems disable only disables the creatures from attacking but doesn’t actually disable the hexproof.
