Mono Blue {Thassa, God of the Sea} is my newest EDH endeavor. Blue staples to include, or any other ideas for a Thassa deck?
Some staples off the top of my head:
{Arcanis the Omnipotent}
{Ertai, Wizard Adept}
{Spell Crumple}
{Hinder}
{Stormtide Leviathan}
{Bident of Thassa}
{Talrand, Sky summoner} (if instant/sorcery heavy)
{Inundate}
{Lorthos, the Tidemaker}
