The Disney Lorcana competitive community is conflicted over whether Bucky — Squirrel Squeaker Tutor should be the first banned card in the TCG.
Bucky has you and your opponent both choose a card in your hand to discard every time a Floodborn card is played. With the Ward ability, Bucky can't be challenged which keeps Bucky's power in play even longer. As a TCG with bad draw power, continuously discarding resources from your hand is a huge problem.
Many Disney Lorcana players have called for Bucky to be banned since the card is making the game feel unfun and unbalanced. Decks that focus on discard as its main strategy are unfavorable to play against — it feels bad. Also, most of the answers to Bucky — cards that can easily remove him, ignore him, or protect hands — are in Steel decks. This has made all other deck types feel irrelevant in the current meta.
