Apparently, the revive trigger (with the "may pay 2") should not be seen by the Roaming Throne (per [this thread](https://www.reddit.com/r/mtgrules/comments/1mbeees/reflexive_triggers_terra_herald_of_hope_and/)), but in XMage I can use it twice. I think it works that way (incorrectly) for many other reflexive triggers.
