Flow is one of Vendetta’s three new mechanics, and it is genuinely one of the more interesting ideas Riftbound has introduced since launch. I had to read the card text twice myself before it clicked, so let’s go through it properly, one step at a time.

How does Flow Work in Riftbound?
Flow is an alternative cost printed on certain Vendetta cards. Once a card with Flow has ended up in your trash, you can play it again later, directly from the trash, by paying its Flow cost instead of its normal cost. You do not return the card to your hand first. It goes straight from the trash back onto the battlefield or into effect.
There is a catch, and it is the important part. After a card resolves through Flow, it gets banished. That means it leaves the game permanently. It cannot go back to your trash and it cannot be Flowed a second time. So Flow gives a card a genuine second life, but only once.
Official Core Rules wording (updated 17 July 2026): “Keyword on spells. Permission and alternate cost. Play the spell from your trash for its Flow cost instead of its normal cost. Then banish it. One time use per card.”
Worth noting from that wording: Flow is specifically a spell keyword, so it only ever appears on spell cards, not units or other card types.
Flow cards also carry a small trash symbol as part of their card layout. According to the same 17 July Core Rules update, that symbol is not a one-off for Vendetta. It is now a permanent part of Riftbound’s card design and will keep showing up on Flow cards in future sets too.
How Flow Works, Step by Step
The clearest way to understand this is to walk through it with a confirmed Vendetta card.
Step 1: A card with Flow enters your trash the normal way. This could happen because you played it and it resolved into the trash, because it was discarded, or because it was burned.
Step 2: On a later turn, instead of leaving it there, you choose to pay the card’s Flow cost. This is a separate cost from what you would normally pay to play the card from your hand, and it can be cheaper or more expensive depending on the card.
Step 3: The card resolves its effect, played directly from the trash.
Step 4: Once it finishes resolving, the card is banished. It is removed from the game and will not return to your trash. That one use is all you get.
The Flow Card Example: Perfect Execution
The clearest confirmed example so far is Perfect Execution, a Vendetta spell. Its card text reads:
“Ready a unit and give it Assault 3 this turn. (+3 while it’s an attacker.) Flow 3 Calm: You may play this from your trash for its Flow cost. Then banish it.”
This card actually does two different jobs. Played normally from your hand, it readies a unit and gives it Assault 3 for the turn, a solid combat trick on its own. But once it has landed in your trash, whether from being played or from being discarded, you get a second option. Pay 3 Calm energy, the Flow cost, and you can play it again straight from the trash for that same ready-and-Assault-3 effect. Then it is gone for good.
That is the appeal of Flow in one card: value now, and a second chance later, at a price and only once.
Burn is the mechanic that most commonly puts cards into your trash on purpose. See How Does Burn Work in Riftbound for the full explanation.
Empower is a separate new Vendetta mechanic, built around spending extra energy to unlock a stronger version of a Legend’s ability rather than replaying cards from the trash. See How Does Empower Work in Riftbound if you want all three new mechanics covered together.
Flow vs Recycling: What Is the Difference?
If you have already read up on Riftbound’s existing Recycling mechanic, you are right to ask how the two compare, because they sound similar at first.
Recycling sends a card to the bottom of your deck, so you might draw into it again naturally later in the game. Flow does something completely different. It works from your trash, not your deck, and it lets you play the card again directly rather than waiting to draw it. The two mechanics interact with different zones and solve different problems: Recycling is about reshuffling resources into your draws, Flow is about getting one guaranteed extra use out of a card that has already done its job once.
Key Flow Rules to Remember
| Rule | What it means |
|---|---|
| One use only | The card is banished after resolving via Flow. It cannot be Flowed again. |
| Must already be in your trash | Flow is not usable straight from your hand. The card has to have already been played, discarded, or burned first. |
| Separate cost | The Flow cost replaces the normal cost. You are not paying both. |
| Played from trash, not hand | The card is not returned to your hand before you play it. It goes directly from trash into effect. |
Which Cards Have Flow in Vendetta?
Perfect Execution is the confirmed Flow card so far, revealed during Vendetta’s preview season. More Flow cards are expected as the rest of the set is revealed between now and the July 31 release. For everything confirmed about Vendetta so far, including champions, new keywords, and product details, check the Vendetta hub, which is updated through the preview window.
If you want the full visual keyword reference alongside this, RiftboundSymbols.com’s keyword index covers Flow, Burn, and Empower together in one place.
Flow rewards planning ahead. If you know a Flow card is going to end up in your trash anyway, that is not a wasted card. It is a second play waiting for the right turn.
Final Verdict
Flow is not as complicated as it first sounds, and once you have seen one card work through it, the rest of the mechanic falls into place quickly. If you are getting ready for Vendetta and want to understand exactly what you will be playing with, this is one of the mechanics worth having clear in your head before the set releases on July 31. You do not need to have played a single game to follow this, and now you can explain it to someone else with confidence.
