Konro, the former hero

Vigilance, haste, Bushido
Still got it: after adding konro to your side of the field. Add a +1/1 counter at each of your upkeep phases.
Pyrocrosis: each time konro deals combat damage remove a counter from him after combat.
All I got left: {2}{r}{b} remove all counters from konro. If he had 4 or more, target one creature you opponent controls and deal damage to it equal to knoros power. During your end phase send konro to the graveyard
