“A protector with a design to commemorate the Duelists overcoming the various obstacles and achieving remarkable results. For those who gained great insights from persevering and arriving to their answer.”

By default, this is disabled in Duels, but enabled for Replays. You can enable it for Duels in Settings -> Duel -> Display Card Report, or disable it for your replays in Settings -> Audience/Replays -> Display Card Report

In practice, this seems to overlap with the “Display Card Effects” setting (the one that shows which effect has just been activated), but maybe that’s just something on my end.

In addition, the following cards have been stealth-added to the Legacy Pack:
Dice Dungeon (SR)
Dimension Dice (SR)

Thunder Ball (R)
