If you ask experienced auto-battler players what separates good play from average play, the answer almost always starts with economy.
Not because economy is flashy. It is the opposite — it is quiet, structural, and easy to ignore. But in Deep Sky: Tracers, how you spend your credits is the single biggest factor in whether your board hits its power spikes on time or falls behind.
This guide breaks down the economy system and shows you how to think about credits as a planning tool, not just a spending resource.

What your credits actually need to do each turn
Every turn, your credits are competing for multiple jobs at once:
- Buying glitches — 2 CR each. These are your combat units.
- Buying chips — 2 CR each. Equipment that defines your units' roles.
- SCANning — 1 CR per reroll. Looking for specific pieces.
- Upgrading Network Tier — 4 / 6 / 8 / 10 / 12 CR. Opens access to stronger shop offers.
- Saving for carry-over — up to 3 CR rolls into the next turn.
Your base credits per turn scale with the match: 6 / 8 / 10 / 12 / 14 from turn one to turn five onward. That sounds like a lot by mid-game, but once you factor in tier upgrades and chip purchases alongside unit buys, 14 CR disappears fast if you are not intentional.
The key insight: your credits do not just buy things. They buy timing. A tier upgrade this turn means stronger offers next turn. A saved 2 CR now means more flexibility tomorrow. Every spend is a tradeoff against future options.
Buy vs save vs tier up
This is the decision that shapes most Recruit phases, and there is no single correct answer. It depends on your board state, your tier, and what the shop is offering.
Here are the situations where each option tends to make sense:
Buy when the shop has a piece that directly improves your current board direction. A unit that completes a synergy threshold, a chip that fills a role gap, or a strong standalone piece that stabilizes a weak turn.
Save when nothing in the shop matches your plan and you would rather start the next turn with extra credits. Carrying 2-3 CR into a turn with better shop access (after a tier upgrade, for example) often produces more value than buying filler now.
Tier up when your board can survive one more combat at its current strength and the next tier unlocks a cost band that your comp wants. Tier upgrades are investments — they do not improve your board immediately, but they improve every shop you see afterward.

A common mistake is treating tier upgrades as something you do whenever you can afford them. A better approach is to ask: will the next tier's shop access help my specific board? If your direction needs cost-4 or cost-5 glitches, upgrading to the tier that unlocks them is a clear investment. If your board mostly wants cost-2 and cost-3 pieces, rushing tier may not help.
How carry-over credits change planning
Unspent credits carry over into the next turn, capped at 3 CR. This mechanic is easy to overlook, but it quietly changes how you should plan every Recruit phase.
Carrying 2-3 CR into a turn effectively gives you a head start. On turn three, for example, you normally receive 10 CR. If you carried 3, you start with 13 — enough to buy two units, a chip, and still have 5 CR left, or to tier up and still buy a key piece.
The habit that helps most: before spending, ask whether this is a spend turn or a setup turn. A spend turn is when the shop matches your plan and you buy aggressively. A setup turn is when you buy minimally (or not at all) and carry credits forward to make the next turn stronger.

Selling also plays into this. Selling a unit refunds 1 CR. If you have a bridge piece that served its purpose and your board direction has moved past it, selling it before a tier upgrade turn can tip the math in your favor.
When SCAN is worth paying for
SCAN costs 1 CR per use with no limit. That makes it tempting to reroll aggressively when the shop looks bad. But every SCAN is a credit you did not spend on a unit, a chip, or a tier upgrade.
SCAN is worth it when:
- You are one specific piece away from a synergy threshold or a key upgrade.
- Your board has a clear direction and the current offers do not match it at all.
- You have surplus credits this turn and can afford to invest 1-2 CR in better options without sacrificing your plan.
SCAN is usually not worth it when:
- You have no clear direction yet — rerolling without a target is just burning money.
- You are tight on credits and every CR is already assigned to buys or tier.
- You are fishing for a specific rare piece with low odds — that CR is often better spent on what is available.

CACHE (locking a shop slot for free) is the quieter alternative. If you see a piece you want but cannot afford this turn, CACHE it and come back next round. No CR cost, no waste.
Why economy and board strength must stay connected
The most common economy mistake is treating credits as an isolated system. In reality, economy and board strength are two sides of the same loop.
If your economy is strong but your board is weak, you take too much hero damage from lost combats. Hero HP starts at 30, and hero damage scales with the winner's tier and remaining board strength. Two or three bad losses can end a match even if your economy plan is perfect.
If your board is strong but your economy is wasteful, you hit a ceiling. You cannot tier up on time, you miss key shop windows, and your board plateaus while opponents scale past you.
The balance point is different every game. Some matches reward aggressive early spending to stabilize HP. Others reward patient saving for a big mid-game spike. The principle stays the same: spend with a purpose, save with a reason, and make sure your board can survive long enough for your economy plan to pay off.

A useful checkpoint: at the end of each Recruit phase, ask yourself — did I spend with intention, or did I just react to whatever the shop showed me? If you can answer that honestly, your economy will improve fast.
