Problem
Too many cards, not enough to do with them.
Players were accumulating duplicates and unwanted cards, but had no satisfying way to convert them into value.
Without a meaningful sink, collections became cluttered, and duplicates felt like wasted rewards.

Solution
Swap to unlock
Introduced a card swap system that let players trade in surplus cards for new packs - turning clutter into anticipation.
To support this, I designed a smart filtering interface that made it easy to find eligible cards for swaps. The system doubles as a visual checklist, helping players track requirements and spot collection gaps.
