: Search your library for a Dragon permanent card and put it into your graveyard. If you do, Scion of the Ur-Dragon becomes a copy of that card until end of turn. Then shuffle your library.
When Scion of the Ur-Dragon becomes a copy of another Dragon, it loses its copy ability for the rest of the turn.
Removing the other Dragon card from your graveyard has no effect on Scion of the Ur-Dragon.
