That's not a good argument, Hysteric Spear is costed, not guaranteed to appear (just like Medusa) and relies on leaving the center open, even though Danger is good at doing that, Medusa allows you to attack with penetrate from the left/right while keeping a center monster like Hellhound for some defense, and a deck focused on penetrate can run more than 1 penetrate card to make it easier to have one.
