Does Brutalizer's text work correctly when it uses 'this' to refer to itself, given that the text is granted to the attached creature?

Ruling: Brutalizer's wording is correct and functions as intended. When the text refers to "this," it means "this gear" (Brutalizer itself), not the attached creature. There is no functional difference between Brutalizer's wording and Guardian Angel's more explicit wording.

Nuances:

• Guardian Angel spells out its name for clarity, but this is an exception rather than the standard templating
• The shorter "this" wording was chosen to save characters in the small effect text box
• The wording prevents multiple Brutalizers from stacking their effects simultaneously
