4 Reaver Hunters and 2 Sile de Tansarville on board?

So on first round guy used Operator to clone Reaver Hunter. On the 3rd round he played Dijkstra, and first and second card were both Sile de Tansarville. How is this possible? 2 copies of same silver card would be possible with Operator but he used him on Reaver. Is there something I'm not aware of? I noticed that even the opponent was really confused when he drew second Sile.

Operator creates a copy of Reaver Hunter, while Summoning Circle can create a second Sile de Tansarville.

Thanks a lot! I didn't think about the circle. It simply gave him second Sile, there was no info about the circle. Still, valid situation.
