Duplicate Bonuses & Combining
Pulling a duplicate of Frostbound Brooch from a pack adds a spare copy to your collection. Spend spare copies in the Cards tab to combine and raise its level — each level costs a number of copies equal to the card's current level. Reaching the maximum level of 12 from level 1 requires 66 total copies. Read the full Duplicate Cards & Combining guide for the general combine mechanics, or use the Combine All button in-game to apply every possible level-up across your whole collection at once.
Evolution
Tycoon Cards does not currently have a card evolution system — Frostbound Brooch progresses only through the standard duplicate-combine mechanic described above. Evolution is listed as a researched feature on our Updates & Roadmap page; this page will be updated if it's ever implemented.
Fusion
There is no cross-card fusion system in Tycoon Cards today. Every card, including Frostbound Brooch, is levelled independently using its own spare copies — you cannot combine it with a different card. Like Evolution, this is tracked as a possible future system on the Updates page.
Collection & Faction
Frostbound Brooch belongs to the Travel collection — one of the thematic groupings used across the card archive. Browse every card in this collection from the main Card Guide, or see the "Related cards" section below for direct links to its closest siblings.
Businesses That Synergise
Cost-reduction bonuses compound with every purchase of a business you buy in bulk. They matter most on cheap, frequently-repurchased tiers where the 15% per-copy cost curve adds up fastest.
| Business | Base cost | Income/s |
|---|---|---|
| 🍋 Lemonade Stand | $15 | $0.1 |
| 📰 Paper Route | $120 | $1 |
| 🚿 Car Wash | $1.30K | $8 |
| 🍕 Pizza Shop | $14.0K | $47 |
Prestige Interactions
Business cost is calculated as baseCost × 1.15^count × (1 − costBonus), independently of your prestige multiplier. This card makes businesses cheaper on every single run, including immediately after a fresh prestige reset.
Best Strategies
- Combine duplicates as soon as you get them — cost reduction compounds with every future business purchase, including on your very next prestige run.
- Prioritise this card above click-only cards of the same rarity; the savings apply across all 100 business tiers.
- Starter Packs are the most efficient way to farm duplicates of this card thanks to its lower rarity.
