Eluge, the Shoreless Sea

Legendary Creature — Elemental Fish

Eluge's power and toughness are each equal to the number of Islands you control. Whenever Eluge enters or attacks, put a flood counter on target land. It's an Island in addition to its other types for as long as it has a flood counter on it. The first instant or sorcery spell you cast each turn costs (or ) less to cast for each land you control with a flood counter on it.
