Isoldia's Lightning Bolt

Inflict 12 damage to any target creature. If there
is any excess damage, inflict that damage to
another target creature, if there is any more
excess damage inflict that damage to another
target creature and so on. If any creature survives
any damage from this card, tap them and place 2
stun counters on them.
Isoldia turned the fearsome bone dragon into bonedust,
along with every other undead in the tomb.
