Rock Hammer Reference Ability Help

[178269]

For Subterra, is Your gate attribute Bonus doubled and Your opponent?
Or is it just you?

[Stronger]

First of all that is totally not even one of Rock Hammer's Ability's, it is Battle Turbine if I'm not mistaken. And secondly, it doubles the Gates, and if your opponent gets a Gate Bonus then they would get the doubled Bonus.

[Esk]

Rock Hammer's Subterra Ability is to lower all Gate Bonuses for both players higher than 100 down to 100 (so if you have like, a 100 boost, and your opponent has a 200 bonus, they only get 100 while nothing happens to you).
