Wizards of the Coast like reprinting old bombs. This Human is very similar to Man-o'-War, a card from the Visions set. It's a perfect choice for a mono-blue Wizards deck that could splash for white or red in case there is a rare or mythic bomb in your pool.
If you played Wizard decks in Dominaria, then you should remember the card named Academy Journeymage. Well, it's basically the same but cheaper and easier to trigger.
