The hope here is to attempt to place more than one Thassa, God of the Sea in a control deck and make it competitive.
My take:
Thassa, God of the Sea - Powerful card. At 3 CMC and invulnerable to most common removal aside from Path to Exile. She lets us filter our draws each turn which seems to me to be a powerful effect in a control deck. Combine that with an unblock able threat to grind out a game, or potentially Thassa herself delivering a beating.
THASSA ENABLERS
--Jace Beleren - Great draw power, especially against decks that don't pressure too fast. Provides 2 Devotion.
--Spreading Seas - Awesome tempo play. If it's not relevant you at least get a card, and 1 Devotion to blue.
--Font of Fortunes - New from JOU. 1U, Enchantment, "1U+Sacrifice Font, Draw 2 Cards".... Could be good I think. It provides another precious devotion which this deck really needs. My thoughts are you play it when you get a chance and have it sit around until you need it. Late game it's a cheap investment, early on it's situational.
--Vendilion Clique - Very fragile devotion, however it's one of the best blue creatures in modern. Powerful disruption with a nice flying beatstick. 2 Devotion
--Voidmage Prodigy - Pretty good here. 2 Devotion, can be a surprise first time you play him morphed. Snapcaster Mage Can be sacrificed as well. Hard counter with devotion.
THE REST- Counters
--Mana Leak - It's Mana Leak
--Remand - Because we lack powerful removal we'd rather put threats into graves rather than back into hands. Acts as the 5th mana leak, also can be nice vs. control. Remand your own countered spell and reap the rewards. Especially if they try to counter with a cryptic.
--Lightning Bolt - Ok so I lied it's not strictly mono-blue. But it mostly is, a red splash is necessary I think. Bolt provides cheap removal for most early creatures in modern and it provides reach. Bolt, Snapcaster, Bolt can help to close out games.
--Spell Snare - Depends on your meta, I mostly play online so it's pretty decent. Could be some number of Spell Pierce or naught at all.
--Cryptic Command - Best counter. So much win with this card. In mono blue it fits like a glove.
--Vapor Snag - Our only real answer to anything above 3 toughness... Ohh well.
Snapcaster Mage For everything above, but twice.
