This is a mono-blue control/lockdown deck. If this isn't your cup of tea, which I understand it's not for everyone, then move on. If you're interested in learning mono-blue control strategies or want to run this deck then read on!
I was tired of playing against Rakdos removal decks with my Radha Gruul deck, so I decided to make the "Anti-Deck" because admittedly, I was getting pretty salty about Radha being a lightning bolt for removal spells, but that's obvious! This deck is nothing but counter-spells, bounce effects, and all sorts of annoying shenanigans that will make your opponent concede through sheer frustration.
Strategy: Charix is the commander here. For this strategy he will be a big wall for us most of the time, and a really hard hitter in the late game. Charix is also 4 mana, so you need to know when to cast him or hold up mana. He acts more like a back up interaction piece when you flood out, but there's been plenty of games where I haven't even cast him because I don't need to. The deck isn't built around Charix so keep that in mind, he's useful but not necessary. Next is the counter-spells/lockdown. If you're new to control strategies then this deck might take some time to learn. You don't always counter-spell everything that comes your way. There's a great deal in knowing how your opponents deck works for you to be successful in interrupting their key pieces. Remember your life total is a resource and sometimes it takes me getting down to 4 life for me to make something happen that wins the game. As with all decks there's some weaknesses. This deck struggles with Simic Verazol decks and graveyard recursion decks. You need to change your strategy to an aggressive aggro-blue deck, using Charix as a beat stick and saving the counter-spells for their game-ending/going off spells. If you let them go wide too fast then they'll over-whelm you with tokens. If you counter the tokens too early then they'll start casting giant kicked spells that you wish you kept your counter spells for. Find the balance to swing in with Charix, leaving yourself open for their attacks, while holding counter-spells for their key pieces.
Over-all this is the most mono-blue deck I've ever built, and a fun one if you like that kind of stuff. Charix is surprisingly a great commander for this strategy and I see why he was designed the way it was. He's mediocre at best, but let's be honest... When you first saw Charix you probably thought, "wow, another 40 cent rare". He's pretty decent.
