Tiga, of Judgment

Menace
Tiga, of Judgment gets +1/+1 counters on it for
each Cat lover on the field.
Whenever a human enters the battlefield, you
can make that player flip a coin. If it's tails, that
creature is marked a Dog lover. Each time Tiga,
of Judgment leaves the field, destroy all Dog
lovers on the field.
