Keep signal

Black Hole turns every Star gain and every Star spend into AOE pressure, which means ordinary Regent resource cards suddenly start dealing damage too.

Overrate risk

The usual mistake is reading the ceiling and ignoring the shell.

Real breakpoint

Going from three to four damage per Star trigger is a major breakpoint because the card scales with every gain and every spend, not just one action.

Pass signal

Skip it in Regent lists with weak Star flow or in short fights where a delayed engine never gets to cash out.

Editorial Strategy Notes

Black Hole turns every Star gain and every Star spend into AOE pressure, which means ordinary Regent resource cards suddenly start dealing damage too.

Editorial PassMarch 28, 2026
When It Is Worth Taking
  • Take it once the deck already cycles Stars often enough that the power will trigger several times instead of sitting as a slow aura.
When It Is Not Worth Taking
  • Skip it in Regent lists with weak Star flow or in short fights where a delayed engine never gets to cash out.
Upgrade Breakpoints
  • Going from three to four damage per Star trigger is a major breakpoint because the card scales with every gain and every spend, not just one action.
Common Fits
  • Big Bang, Genesis, Child of the Stars, Lunar Pastry, and any shell that spends Stars steadily instead of hoarding them forever.
Common Trap Fits
  • It is weak in Forge-only or low-Star decks that want Regent cards without actually running a Star engine.

Decision Breakdown

Card Decision Breakdown

The short panel above is the fast answer. This section slows the judgment down: where the card is live, where it is bait, and which next decision actually changes the call.

Why Pick It

Black Hole turns every Star gain and every Star spend into AOE pressure, which means ordinary Regent resource cards suddenly start dealing damage too. Take it once the deck already cycles Stars often enough that the power will trigger several times instead of sitting as a slow aura. Best homes include Big Bang, Genesis, Child of the Stars, Lunar Pastry, and any shell that spends Stars steadily instead of hoarding them forever. When that support already exists, Black Hole stops being theoretical upside and starts changing the next few fights immediately.

Why Skip It

Skip it in Regent lists with weak Star flow or in short fights where a delayed engine never gets to cash out. It is weak in Forge-only or low-Star decks that want Regent cards without actually running a Star engine. Black Hole drops fast once the run no longer needs the exact job it was drafted to solve, which is where a premium-looking text box turns into dead weight.

Breakpoint

Going from three to four damage per Star trigger is a major breakpoint because the card scales with every gain and every spend, not just one action. That breakpoint only matters if it changes smith priority, turn sequencing, or the damage math you expect to face next. If that shift is not changing a real decision right now, the premium story is mostly cosmetic.

Best Shells

The clean homes are Big Bang, Genesis, Child of the Stars, Lunar Pastry, and any shell that spends Stars steadily instead of hoarding them forever. Black Hole wants a shell that can cash the upside on the same turn or the same cycle it matters. Those decks convert the text into tempo, stability, or a faster kill clock instead of waiting several fights for the promise to come true.

Bad Shells

It is weak in Forge-only or low-Star decks that want Regent cards without actually running a Star engine. Those are the shells that make Black Hole look stronger in draft than it feels in play. Black Hole either arrives too early, lands too late, or asks for support the run never actually built.

Route Context

Route context matters because Black Hole is only premium when it fixes the next failure point instead of adding one more nice idea to a deck that already has too many ideas. The next check is Open Regent Guide. Place Black Hole inside a real Star economy shell instead of overrating it in every Regent list. If the call is still close after that, use Open Regent Stars Calculator. Measure how often your current Star flow actually triggers Black Hole before the fight ends. If the next rooms are asking a different question, verify the line before you spend draft equity, a smith, or route safety on it.

Example Line

Take it once the deck already cycles Stars often enough that the power will trigger several times instead of sitting as a slow aura. The support package already includes Big Bang, Genesis, Child of the Stars, Lunar Pastry, and any shell that spends Stars steadily instead of hoarding them forever. Going from three to four damage per Star trigger is a major breakpoint because the card scales with every gain and every spend, not just one action. That is the version of the run where Black Hole stops being speculative and starts changing what you can safely do in the next room or at the next campfire.

Common Misread

The usual mistake is reading the ceiling and ignoring the shell. Skip it in Regent lists with weak Star flow or in short fights where a delayed engine never gets to cash out. It is weak in Forge-only or low-Star decks that want Regent cards without actually running a Star engine. Black Hole gets overrated when players remember the best-case output but forget how rarely the current deck actually produces that state.
