Slumbering Walker's triggered ability at your end step displays a ORANGE DECLINE button on the right, and expects you to CLICK ON Slumbering Walker to confirm the ability.

This goes against every triggered ability with an option to confirm/decline in the entire game. Other abilities will have decline button in BLUE, not ORANGE.

If I've been taught by the game to press ORANGE to select things that are beneficial to me, why is this ability orange to benefit my opponent?

I understand small case scenarios where I might WANT to decline, but not even HAVING confirm as an option on the right and wanting me to click ON THE CREATURE is downright absurd.

This mistake cost me the game in the attached clip, and this was in the Arena Direct - Sealed Lorwyn Eclipsed Collector Booster Box Event.

PLEASE change this to AT LEAST have the decline button be BLUE.
