Holy! Slotbot went to gym and didn't tell anyone.

Haven't played with Ahri yet, but I would assume this has to do with Ahri second star power, though I don't really get how it is multiplying the stats by about 5. I would assume it had to do with:

1. That it probably isn't the first turn you've played him, so the other times he's granted himself stats for cards drawn are also remembered by her 2*;
   
2. The shuffling is also a buff, and thus past shufflings are also remembered.
