Today I was beating UsUm for the first time. On my way through the final trial, walking through Lush Jungle, I was ambushed by and Fast Balled a shiny Steenee. This was less than an hour after I encountered and caught a shiny Magcargo in Ultra Space. Two in an hour.

I know Ultra Space shinies are common (~3%) but are ambush encounters boosted too? Am I just a lucky guy today?

Also, tell me about your first time, ya hunks.
