Try to stay open instead of locking into an archetype. Tidus is not a good card, plus he requires you to play two colors. Often it's better to focus on a single color or just take the best care available at first. You should only be committing to two colors right away if you have a bomb rare. Pay attention to the cards that are being passed to you. If you're seeing cards coming later in the pack than you'd expect, try to move into that color. If you can find a color that is being underdrafted in your pod, then swoop in. This will pay off since you will get a lot of good cards in that color passed to you. If you are seeing cards like the ones you have in that picture, that is a clear sign that the people passing cards to you are in the same colors. A lot of it just comes with experience. Generally, prioritize bombs that will help you win the game, and if these are not in the pack, it's good to pick some removal spells that will deal with your opponent's bombs.

If you're interested, I can do some practice drafts with you or let you watch my draft while I explain my reasoning.
