Seascape Visionary

Infiltrate (As long as this permanent is on the battlefield, target opponent reveals a non-revealed
card from their hand)
When Seascape Visionary enters the battlefield,
reveal the top four cards of your library. If you
reveal an Island this way, put a flood counter on
target land. Lands with flood counters lose all
types and abilities and are Islands. Then, put all
the revealed cards on the bottom of your library
in any order.
