Just as expected from mono-U you want to keep the board in check and win the game through incremental card advantage. A huge step into that direction is getting Bident of Thassa, Coastal Piracy or especially Kindred Discovery on the board and then proceed to draw a gazillion card via your flyers.
With the rule change Teferi's Protection brought us - Tokens being able to phase in again - Teferi's Veil turned into a more than solid card in this deck. Talent of the Telepath is also crazily overlooked, as it can be 2 great spells and 3 triggers all in one. I also love Soothsaying for the simple fact that it allows me to use unspent mana eot before my turn and vastly improve my draw that way.
Let me know what you think of the deck! I'm always happy to get input.
