So what? Blue shouldn't be able to interact with creatures? Never mind Control Magic effects beats most removal spells, especially in limited environments, but somehow that evades people's attention.
Bounce effects act as removal, tap down effects act as a temporary solution.
They already have ways to interact, and one could argue that they have the most ways to do so.
Control magics are fine because they're usually costed appropriately and can be destroyed in most cases. Plus the ability is super blue.
