Before following up Red Onslaught, decide what you want to preserve. Copying his text, repeating his existing abilities, and copying the whole card can give you different results. A follow-up that starts another random roll won't reliably carry the particular ability that made your first Red Onslaught useful.
Red Onslaught's official card spotlight gives his text as “Ongoing: Has 3 random Ongoing abilities.” The question is whether a follow-up creates another random selection or works with the abilities already selected.
That distinction runs through the September 4 Marvel Snapcast discussion. The episode compares Mystique and Onslaught with whole-card copies from Arnim Zola or Sinister London. Super-Skrull gets a separate explanation.
What each follow-up is trying to do
These are the Red Onslaught cases described in Episode 155, rather than a rule for every card with copying text.
| Follow-up | Operation described in the episode | What happens to Red Onslaught's result |
|---|---|---|
| Mystique copying the text of the last card you played, if it has an Ongoing and she can copy it | Creates a new instance of the random-ability effect | Rolls again; a result can match the earlier roll |
| Onslaught affecting Red Onslaught in the same location | Makes the existing Ongoing abilities happen an additional time | Uses the abilities already selected, rather than selecting another set |
| Arnim Zola or Sinister London copying the card | Copies the card with its existing abilities | Preserves that card's selected abilities in the copied version |
| Super-Skrull facing an enemy Red Onslaught | Receives the selected Ongoing abilities | The episode distinguishes this from receiving another random Red Onslaught roll |
The useful first check is the actual text of the follow-up you're considering. Mystique, Onslaught, and Arnim Zola have different jobs. Their other requirements still matter; a copying interaction isn't a promise that the target or destination will be available. Use the MARVEL SNAP card library to compare the full named effects.
Mystique gives you another roll, not guaranteed novelty
The early Good or Garbage review highlighted the surprise of Mystique producing another set of abilities. Episode 155 makes the qualification explicit: the new roll can produce the same result.
That matters in both directions. Don't choose Mystique on the assumption that she will preserve one specific ability you already rolled. Don't choose her on the assumption that every ability must be different, either. A fresh random operation can repeat an earlier outcome.
If your play needs a particular effect, another roll introduces uncertainty about that effect. If you're choosing to accept that uncertainty, make it part of the decision before committing to the follow-up.
Onslaught works with the result already there
The episode describes Onslaught as making Red Onslaught's existing abilities happen an additional time. It doesn't describe him as expanding the number of randomly selected abilities.
That makes the current result relevant to the decision. Read what Red Onslaught actually has, then ask whether repeating those effects helps the board you're trying to build. More activity from an effect isn't automatically useful in every location or game state.
This is also why multiplying a random-effect card's printed description is a poor shortcut. First establish whether the follow-up repeats the selected effect or creates another selection.
A copied card can retain its abilities and still face a different board
Arnim Zola and Sinister London are the whole-card examples in the September 4 explanation. They preserve the selected abilities in the copied card, according to the discussion.
Preserving an ability doesn't mean every location produces an identical outcome. The ability's conditions still have to be read in the place the copy reaches. Before using a copy to contest another location, check what that ability will actually do there.
Treat Super-Skrull as its own case. The episode says he receives the enemy Red Onslaught's selected Ongoing abilities. That doesn't turn every card that borrows an ability into a whole-card copier, and it doesn't supply a rule for every other random-effect interaction.
Start with the result your next play requires. If you need to retain an existing effect, another random roll is a different plan. Watch the full copying discussion in Episode 155 for the comparison, or find related coverage in the MARVEL SNAP card reviews collection.
