Tobi Kadachi

Flash
When Tobi Kadachi enters the battlefield, tap all opponent's creatures that were dealt damage this
turn. If they are already tapped, they do not
untap during their controller's next untap step.
A fanged wyvern that flies among the trees of the
Ancient Forest. Its penchant to brush against
the ground and the trees as it moves around builds up
static electricity within its fur.
