Eluge, The Shoreless Sea

Eluge's power and toughness are each equal to the
number of island you control.

Whenever Eluge enters or attacks, put a flood
counter on target land. Its an island in addition to
its other types for as long as it has a flood counter.

The first instant or sorcery you cast each turn
costs {u} (or {1}) less to cast for each land you
control with a flood counter on it.
