You've Got a Friend in Me

At the beginning of your upkeep, put a
friendship counter on target creature you
control.
{x}{w}: The next X damage that a source of your
choice would deal to target creature with a
friendship counter on it you control this turn is
dealt to another target creature with a friendship
counter on it instead.
