Hello everyone - I'm torn between three decks that I could take tonight and I have come to you for help. I would prefer to just stick to cards that I already have, but if I have to try to find stuff at the shop today I can do that too, he just may not have some of the cards I'd be after. We'll say max to spend on new cards will be $20.

As I've offered on Reddit before, for the person whose suggestions I take and use, I will split anything I win with that person as a thanks for their help.

All decks are linked to my profile

I'm not quite sure what I'm in for with the store I'd be playing at - this will be my first time playing at this shop but I do know there tends to be quite a few people.

Deck 1: Boros Beatdown
Probably the strongest of the options, it just tends to play best of the three. Sideboard help for replacement of the O-
Rings and/or any other suggestions are welcome.

Deck 2: Izzet Ingenuity
My favorite of the three, just fun to play. I'd like to make it more consistent. Also, Sideboard.

Deck 3: Simic Advantage
Relies on counters for card advantage, and then overwhelming. Fliers are a pain in the neck for this deck. Also, sideboard.
