What about developing the fact that all your spells are blue?

If it's an Elder Dragon Highlander Deck, as I suspect it is, the guidelines for this deck variant only allow colorless cards and cards that are the same color/colors as your general (even more specifically, cards that produce mana or have costs outside of the general's color/colors are not allowed). With Arcanis the Omnipotent as his "General", he will only be able to use blue or colorless cards.
What I meant is use cards like Ablution that specifically aid mono blue decks. Gauntlet of Power would be another good one to use.
My mistake. Extraplanar Lens could be helpful in this respect.
