Marvel Snap Red Onslaught Simulator

Red Onslaught is a 4-cost, 4-power card whose Ongoing gives him 3 random Ongoing abilities pulled from a fixed pool. This simulator rolls those 3 abilities so you can see what he might become before the card releases or before you spend tokens to craft him. Tap the card to roll, watch each result reveal in sequence, and read the full ability text for every card he copies. Below the roller, an Included Cards grid lists every card in his pool sorted by cost, and tapping any card opens its full detail with stats and release info. If you sign in and sync your collection, results show your equipped variant art instead of the default renders.

How Red Onslaught's Ongoing pool works

Red Onslaught does not copy every Ongoing card in the game. He draws from a specific pool of 54 Ongoing cards confirmed through the datamined game data, and this simulator uses that exact list. With 3 abilities drawn from 54 cards each roll, any one specific card has roughly a 5.5% chance of showing up in a given roll. Some hits are game-defining: Onslaught doubles your other Ongoing effects, Iron Man doubles your total Power at his location, Blue Marvel gives your other cards +1 Power, and Cerebro pumps your highest-Power cards. Others do little for a given board. Because the 3 picks are independent every roll, the card swings hard between busted and useless, which is exactly what the simulator is built to show you.

Roll, share, and browse the pool

After each roll, copy a branded 1200x630 share image straight to your clipboard for posting to Discord, Twitter, or anywhere else. The image shows all three copied abilities with SnapComplete branding, sized for social previews. Your roll history saves up to 200 previous rolls in a table, with per-row share buttons so you can go back and grab a standout result. The Included Cards grid gives you the full pool at a glance, sorted by the same cost order the rest of the site uses, and every card links straight to its detail view so you can check power, series, and release status without leaving the page. The simulator is fully free with no daily limit and no premium gate.

What to look for when evaluating Red Onslaught

Run 20 to 30 rolls and watch how often Red Onslaught lands a stack of Power-multiplying Ongoings versus a set of narrow location effects that do nothing for your plan. Onslaught is the roll everyone wants, because doubling your other Ongoing effects turns a board of small buffs into a blowout, and pairing it with a Power doubler like Iron Man is where the card gets absurd. Most rolls are more modest, and plenty are duds, so the simulator is the fastest way to build realistic expectations before he is in your collection. Since he pulls from the datamined pool the game actually uses, what you see here is what you would face across the table. Pair it with the Rama-Tut simulator for the On Reveal version of the same random-ability idea, or browse the full card database to study every Ongoing card in his pool.
