Making it mono blue to simplify things (there's also not space for red with 40 cards). I may add a custom blue bounce land and scry land later.
Mystic Retrieval was either useless or OP depending on who had access to red.
Accumulated Knowledge was snowbally and there's less room for it now that the stack is 40 cards. I've added more cards that have an effect while drawing a card, like Complicate, Remand, Repulse, and Telling Time to hopefully fill the card advantage hole.
Dance of the Skywise has less utility than March of Swirling Mist, similarly for Mind Bend -> Piracy Charm.
Mystical Tutor had the incentive to look through the deck to deduce your opponent's hand.
This change removes a land because both players start with 2 Islands in play and I lowered the curve, but I may have to add back a land.
