I do not know if this was a one-time bug or if this always happen, but happened to me that I got Sportacus thanks to Cornucopia, and at that same turn, with Spartacus there, my opponent played THREE trick cards and Sportacus did NOTHING.
I tried to wait to get Sportacus a second time through Cornucopia, to check if the error happens every time it is invoked by him, but today, that I just got it again, my opponent did not do any trick, so I could not prove it. And I think waiting for a third occasion is too much...
