Hero Killer Stain

Vigilance, haste
Permanents with blood counters on them can't
attack and lose all abilities.
At the beginning of your upkeep, remove all
blood counters from all creatures.
{r}{w/b}: Stain deals 1 damage to target creature or planeswalker. Put a blood counter on that
permanent. Activate this ability only if Stain has attacked this turn.
"I will reform this city. In order to do so, I require
more victims."
