If you play under the Japanese locale, you will see a redundant "＠" sign in the text box of Valley Rally (渓間の結集).

This issue is not usually harmful, (except for cases that, e.g., a novice Japanese-speaking player could be confused by considering it has some important meaning in the game play and wondering), but a bug is a bug.

Steps to reproduce the bug

1. Run MTG Arena under the Jaspanese Locale (Adjust Options > Graphics > Locale > 日本語 (Japanese). You may need to exit and restart the game for the change to take effect.)
2. Find the card 渓間の結集 (Valley Rally) in your collection (デッキ (Decks) > コレクション (Collection)) by, e.g., using Advanced Filters and checking Red, 3, Collected, Not Collected, Instance, and Bloomburrow.
