With all these things and the balance of creature to noncreature spells, Primeval Bounty can do anything you need
These are just a taste of the alternate win cons available, and I highly recommend checking the rest out to see if any are up your alley, as there is no greater feeling than cinching the win outright with an unusual you win the game ability when others thought you were out of the picture - and what else should we aim for, if not making our games more memorable?
Sure, Katara, Waterbending Master is a mere 1/3, but blue decks already hold up interaction on opponents turns anyway, so accumulating experience is the easy part
If blue gets involved as a primary or secondary color, the profile of the deck tends to shift more towards tempo using more interaction cards like Aether Spike and ground blockers like Emissary of Soulfire to slow down opponents while your flyers do the damage
Often in EDH you'll just want a 1-mana cantrip to fuel some storm or Izzet shenanigans
