The options for Starter Decks are Amethyst and Amber, Emerald and Ruby, or Sapphire and Steel
Some decks rely on the devotion mechanic, with Master of Waves, Thassa, God of the Sea, and Thassa, Deep-Dwelling offering good payoffs for having many blue symbols around
The biggest problem with it is being in both white and blue really restricts the amount of decks it can go in, and since you're in blue you likely have better draw engines
