Rating & Analysis
Diet Cola awards a free Double Tag on sell — and Double Tag duplicates the next valid Tag you encounter. At $6 Uncommon, treat it as a disposable Joker and sell it for the Tag.
The dream pairing is the Double Tag loop: stack a Double Tag, then take a Negative Tag for a free Negative Joker — you get +2 Joker slots and 2 free Negative Jokers off one play. Boss / Investment / Economy Tags also benefit massively from duplication (Boss skip ×2, +$50 from Investment, etc.).
Watch out for Eternal Diet Cola — un-sellable means dead weight. Double Tag also duplicates Orbital / Standard Tags for hand-level / pack value. Tier lists rate A overall, S in Double-Tag-loop builds. The textbook line: buy on sight, then sell the moment a strong Tag is queued.
Deck Ratings

| Black | S | +1 Joker slot — Diet Cola + Negative Tag = +2 net |
| Red / Blue | A | Standard Tag-axis build |
| Yellow | A | $6 trivial vs starting capital |
| Ghost | A- | Spectral builds branch differently |

Tips & Usage
- Buy on sight. $6 for a guaranteed Double Tag is a steal.
- Sell right before a strong Tag is queued — the next valid Tag duplicates.
- Negative Tag duplication = 2 free Negative Jokers + 2 slots.
- Boss Tag duplication = 2 boss skips + 2× rewards.
- Investment Tag duplication = +$50 economy spike.
- Avoid Eternal — un-sellable Diet Cola is dead weight.
Caveats
- Eternal Diet Cola is dead weight — un-sellable.
- Double Tag duplicates the next valid Tag — sell timing matters.
- Selling consumes the Joker slot — plan refill (Riff-raff, Negative Joker).
- Free Tags ($0) gain nothing from duplication.
- Perishable still works as a sell-target, but value depends on shop timing.
