How the 7 Stones Energy System Works: Stone Energy, Generic Energy, and Real Trade-Offs
Each turn, choose one flexible Stone Energy or two faster Generic Energy. This guide explains the accumulating trade-off, a worked decision, and the limits of reduced variance.
The 7 Stones Energy System gives you the same decision at the start of every turn: take 1 Stone Energy or 2 Generic Energy. Stone Energy can pay Stone or Generic costs. Generic Energy can pay only Generic costs. Stone gives you flexibility; Generic gives you more total energy.1 2
Your Energy Pool grows as the match continues, so the choice affects more than the current turn. Every decision changes the mix of resources available for the plays you may want later.
The Energy choice at a glance
7 Stones uses 30-card decks with no land cards. Energy comes from the choice you make each turn instead of from a dedicated card draw. The public rules say the pool keeps growing with no stated maximum.1 2
| Start-of-turn choice | Added to your pool | Pays Stone costs? | Pays Generic costs? | Main benefit |
|---|---|---|---|---|
| 1 Stone Energy | 1 | Yes | Yes | Keeps Stone requirements available |
| 2 Generic Energy | 2 | No | Yes | Builds total energy faster |
Neither choice is automatically correct. Taking Stone costs you one unit of immediate growth. Taking Generic leaves your Stone capacity unchanged. The better choice depends on the play you are trying to set up.
When Stone Energy matters
Stone Energy pays any cost, including Stone and Generic requirements.1 2 Take it when the cards you expect to play need more Stone capacity than you currently have.
That flexibility has a price. You receive one energy instead of two, which can delay a Generic-heavy sequence. Before choosing Stone, ask whether the extra flexibility changes a real play or simply feels safer.
When Generic Energy matters
Generic Energy arrives two at a time and pays only Generic costs.1 2 It is useful when the extra unit crosses a meaningful threshold, such as letting you play a larger Generic cost or combine two actions sooner.
A large Generic pool cannot cover a missing Stone requirement. You may have enough total energy on paper and still be unable to make the play you want.
How earlier choices shape later turns
The pool grows turn by turn, so its composition records your earlier decisions. This is cumulative growth, not exponential growth.
After t Energy choices, let S represent Stone turns and G represent Generic turns:
S + G = t- Stone Energy generated =
S - Generic Energy generated =
2G - Total Energy generated =
S + 2G, which is alsot + G
These figures describe energy added before spending or other effects. Every Generic choice adds one more total energy than a Stone choice. Every Stone choice adds capacity that can satisfy Stone requirements.
| First three choices | Stone generated | Generic generated | Total generated |
|---|---|---|---|
| Stone, Stone, Stone | 3 | 0 | 3 |
| Stone, Generic, Stone | 2 | 2 | 4 |
| Generic, Generic, Stone | 1 | 4 | 5 |
| Generic, Generic, Generic | 0 | 6 | 6 |
The all-Generic line has the largest total, but it cannot satisfy a Stone cost. The all-Stone line has the smallest total and the most Stone access. Most real decisions will sit somewhere between those extremes.
A simple turn example
Suppose your first two choices were 1 Stone on turn one and 2 Generic on turn two. Before spending, that gives you 1 Stone and 2 Generic Energy.
On turn three, imagine you are choosing between two abstract lines:
- Line A needs a second Stone requirement.
- Line B uses only Generic requirements and benefits from a larger total.
| Turn-three choice | New generated mix | What changes |
|---|---|---|
| Take 1 Stone | 2 Stone + 2 Generic | Line A becomes available |
| Take 2 Generic | 1 Stone + 4 Generic | Line B gains more total capacity |
If Line A is the play that matters, two more Generic Energy will not solve the bottleneck. If Line B creates the stronger position, taking Stone may slow you down for no immediate gain.
The useful question is not “Which number is bigger?” It is “Which resource is constraining my next play?”

Three habits for better Energy decisions
Count requirements, not only total cost
Look at the Stone and Generic portions of the cards you may play over the next turn or two. Five total energy is not useful if the play needs two Stone and you have only one.
Ask whether the second Generic unit changes the turn
Generic is strongest when its extra unit enables a specific action. If it does not improve the current sequence, Stone may be worth taking to keep later options open.
Plan a short sequence
“Stone now, Generic next” and “Generic now, Stone next” produce the same mix after both choices: one Stone and two Generic. They do not produce the same intervening turn. Order matters whenever timing matters.
Deck construction should inform these choices. A list with frequent early Stone requirements needs a different plan from one whose early turns lean on Generic costs. You can inspect the currently revealed material in the card gallery, but no universal Energy ratio can replace testing a finished deck.
What reduced resource variance actually means
The first-party pages describe this system as reducing variance because baseline Energy is chosen each turn instead of drawn as land or resource cards.1 2 That is a specific claim: Energy acquisition moves out of the deck and becomes a recurring decision.
It does not make every match predictable. Players still begin with a four-card hand, and mulligans replace selected cards with random draws. A replacement can be the same card.2 Draw order, matchups, combat, sequencing, and future card effects can all change the decisions available.
The How to Play page currently says, “You always have a play,” while also stating that the full rulebook and interactive tutorial will ship with the game at launch.2 Until those materials and the playable environment can be checked, treat that line as first-party pre-launch positioning, not a mathematical guarantee about every possible hand or game state.
The Energy System reduces variance in how baseline resources arrive. It does not remove uncertainty from cards, opponents, sequencing, or outcomes.
What is confirmed and what is still open
7 Stones remains a pre-launch project, so published rules and future product statements should be kept separate.1 2
| Status | What the current pages establish |
|---|---|
| Published rule | Choose 1 Stone Energy or 2 Generic Energy each turn. Stone pays Stone or Generic costs. Generic pays only Generic costs. The pool grows with no stated maximum.2 |
| First-party positioning | The game uses 30-card decks without land cards and describes the system as reducing draw variance.1 2 |
| Planned material | A full rulebook and interactive tutorial are described as launch features.2 |
| Not fully specified | The reviewed pages do not define every refresh, payment-order, timing-window, priority, interface, or beta-balance detail. |
Check the official FAQ for current product answers. A newer rulebook or in-game rules text should take priority over this explanation if the terminology changes.
Common questions
Can Stone Energy pay Generic costs?
Yes. The current rules say Stone Energy can pay Stone or Generic costs.2
Can Generic Energy pay Stone costs?
No. Generic Energy can pay only Generic costs.1 2
Is two Generic Energy always faster?
It always adds more total energy from that turn's basic choice. That advantage matters only when Generic capacity can pay for the line you want.
Does the Energy Pool have a maximum?
The current How to Play page says the pool grows each turn with no maximum.2 The complete rulebook should control if that wording changes.
Does reduced variance eliminate bad draws?
No. The system removes dedicated land draws from deck construction, but opening hands, mulligans, and later card draws still involve randomness.2
