Christian, Forever Searching

Trample
Whenever Christian deals combat damage to a player, you may pay {1}{u}{r}{g}. If you do search your library for an instant, sorcery, or creature card, reveal it, put it to your hand, then shuffle your library.
"Where am I now? Since no one has tried to kill me yet this isn't Tarkir. Too dead for Lorwyn. Eitherway I will find my way back to Ravnica. Maybe if I get lucky I'll see that cute elf girl again."
