Saburo

{t}: Put a flood counter on target non-Island
land you control. (That land is an Island in
addition to its other types for as long as it has
a flood counter on it.)
At the beginning of combat on your turn, if you
both own and control Saburo and a creature
named Jiro, meld them into Ichiro. Activate this
ability only if all lands you control are Islands.
Saburo digs holes to reunite with Jiro.
