Pearl Krabs

Pearl Krabs' power and toughness are each equal to the number of Islands you control.
Whenever Pearl 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 {u} (or {1}) less to cast for each land you control with a flood counter on it.
