Charon, the great reflector

Vigilance, protection from red
Stoking the flame: when charon blocks, put a +1/0 counter on him.
The great protector: every time a red creature enters play under your control, Charon gains a +0/1 counter.
Last stand: {6}{r} if a creature you control would be dealt lethal damage as a result of being targeted for an attack from an opponent creature. Change the attack target to Charon and discard both the attacking creature and Chiron.
