This is a “Lockdown Kiora” combo deck idea, based on constant mana drain. It makes very hard for the oponent to cast anything unless it’s cheap (so it “usually” won’t be a big threat) or is played on a single turn (cascade chain or something similar). Classic MtG Blue deck

How to play:
1-. Draw heavily early on to find your lockdown cards. Use Kiora’s 1st for extra mana, 2nd to find buried Meddlers.
2-. Play your lockdown cards. EXILE excess cards for Sphinx draws.
3-. Play your killer.
4-. Play control cards until your killer does it’s job. Control your card draw by keeping an (almost) full hand, so you don’t run out of cards by drawing too much. Use Kiora’s 1st for extra drainage. You can also awaken some elementals if the oponent is locked down enough.
Take note that you should always be able to cast something on your turn, unless the board has bad gems (only four cards of your “basic” lockdown deck have a mana cost higher that 6); also if you have a rank4 Kiora’s 1st skill “saved” you can play any 9-12 cost cards in a single turn with a basic 3-match, that usually allows you to cast anything you want but your “killer” card.
