Smiling Mask
Smiling Mask is a common relic that causes the Merchant to restock cards, relics, and potions after you purchase something, and also reduces the price of card removal to 50 Gold (from the default 75 Gold). The restocking means the shop's selection refreshes, giving you more items to potentially buy in a single shop visit.
The reduced card removal cost is arguably the most significant aspect of Smiling Mask. Card removal — removing bad cards like Strikes and Defends — is one of the strongest investments in the game, and making it cheaper allows you to remove more cards per run, leading to a leaner, more consistent deck. The restocking effect adds more browsing options but rarely matters as much as the removal discount. Smiling Mask is a straightforward but valuable common for players who prioritize deck quality.
