Brushwood Witch

Defender
At the beginning of your upkeep, put a twig
counter on Brushwood Witch.
Whenever you cast a red spell, if there are 3 or
more twig counters on Brushwood Witch, remove
all twig counters from Brushwood Witch. If you
do, Brushwood Witch deals 3 damage to each
opponent and each creature they control.
