It is the first card with the Silence ability, and also the only one until Beta 4.5 with the release of Memorial Statue. Now, Scarf Mouse can also silence. This ability allows you to remove any stat changes, abilities and status effects from the targeted monster. In other words, it makes a monster's stats return to their base and makes it lose their ability.
This will give results such as a 2 HP Garbage and a 1 ATK Flowey that upon death, won't return to the owner's deck. Keep in mind that Magic and Future effects are unaffected by Silencing, and DT cards are completely immune to it (even if the card doesn't say so), meaning that you can't get rid of their ability or reset their stats.
This can be used on your own cards or the opponent's. This card should be saved for later in game when the opponent has likely saved any of its buffing cards, especially if versing Kindness or Bravery.
Please note that when something with a lowered Max HP is silenced, its Max HP will return, but its current HP stays the same (making it damaged). For example, if a Madjick is used on an Ice, the Ice will have 7/1. But if it gets silenced afterwards, it will end up with 1/1 (with a Max HP of 7).
- Nacarat means 'orangey red' in English, which is what colour Nacarat Jester is, as seen in Undertale. But because almost every card in this game doesn't use colour for its images, that is not shown here.
