Flying, first strike
If a source would deal damage to an opponent or a permanent an opponent controls, that source deals
double that damage to that player or permanent instead. If a source would deal damage to you or a permanent you control, prevent half that damage, rounded up.

"Tobit, when you and Sarah prayed, it was I who
brought and read the record of your prayers before
the glory of the Lord." –Tob.12:12
