With Great Power . . .

The redirection clause is doing quiet defensive work that the pump clause disguises. Voltron auras have always paid off attaching-more with bigger numbers, but the second line here rewrites where combat and burn actually land: every point of damage aimed at your face is rerouted into the creature you have been stacking with Auras and Equipment. That inverts the usual Voltron liability. A heavily suited-up creature is normally a target-rich single point of failure; here it becomes a lightning rod that protects your life total, absorbing the damage an opponent's aggression or reach would otherwise spend on you. The tension is that you are consolidating risk onto one permanent that the pump clause has already made valuable, so a well-timed removal spell now costs you both the threat and the shield. The scaling and the redirection also feed each other in a specific way: the more gear you pile on to make the creature hit hard, the more toughness it accrues to survive the damage you are now routing into it. This is a card that asks you to build the fortress and then stand inside it, which is a different proposition than the aura that simply makes a creature large.
