Hoxen, Tired Hero

First strike

Whenever a Cat you control attacks, bolster 1 (Choose a creature you control with the least toughness or tied for the least toughness among creatures you control. Put a +1/+1 counters on that creature.)

Cats you control have exalted (Whenever a creature you control attacks alone, it gets +1/+1 until end of turn for each instance of exalted among permanents you control.)

Oh we have to climb that? Again?
