Cecilia, Toad Rider

Whenever you cast an enchantment spell, if you
don't control a creature named Selkie, create Selkie,
a legendary 3/3 black and green Frog creature token
with "Whenever you cast an enchantment spell,
each opponent loses 1 life and you gain 1 life."

{1}{g/u}: Cecilia, Toad Rider and target Frog you
control can't be blocked this turn except by creatures
with flying or reach.
