Dear Wizards of the Coast MTG Arena Development Team,
I am writing to respectfully request the implementation of an option to toggle off the visual highlighting of cards when an opponent hovers their mouse over them. As a dedicated player who frequently engages with MTG Arena, particularly for ranked play and as a free-to-play participant striving to progress, I find this particular visual cue significantly detracts from my gameplay experience.
My primary reasons for this request are:

• Distraction and Focus: During intense matches, especially when reading complex card text, calculating board states, or strategizing intricate lines of play, the constant flashing and highlighting of cards by an opponent's mouse can be highly distracting. It disrupts my concentration and requires additional mental effort to filter out this visual noise, which can be particularly taxing during extended play sessions.

• Unintended Meta-Gaming/Annoyance: While I understand the intent may be to show activity, this feature is sometimes used in ways that are not conducive to a positive player experience. I've observed instances where players seem to deliberately hover over cards to annoy or mislead, such as repeatedly highlighting a creature I would be forced to sacrifice, even though the choice is ultimately mine. While this doesn't alter the game's outcome, it does introduce an element of unnecessary interruption and frustration.
  A simple "toggle on/off" option in the game settings for opponent mouse highlights would greatly enhance the quality of life for many players who share this sentiment. It would allow players to customize their visual experience to better suit their individual preferences and focus needs, without impacting those who find the feature useful.
  Thank you for considering this feedback. I believe that providing players with more control over their UI experience will contribute to an even more enjoyable and competitive MTG Arena environment.
  Sincerely,
  Chubeelius (Hun)
