Rashja's Guidance

Knights you control have +1/+1.
{w}{b} or Pay 1 life: Tap target creature you
control. It is a knight in addition to its other
types. Activate only as a sorcery.
Pay 2 life: Put a +1/+1 counter on target creature
you control. That creature gains first strike until
end of turn. At end of turn, if that creature
attacked this turn and you still control it, you
may proliferate.
