Start Here: Most Issues Are One of These Two Things
If your shuffler didn’t work the first time you tried it, don’t worry — it's easy to fix.
Almost every issue comes down to one (or both) of these:
- You’re turning the crank too slowly
- The feed height needs a small adjustment
Before changing anything else, try turning the crank faster and smoother. You can’t really go too fast.
How the Card Feed Works (Quick Explanation)
Cards enter the shuffler at a slight angle and are pulled forward by spinning rubber tires. The size of the gap above those tires determines how many cards can pass through at once.
That gap is controlled by two adjustable parts called the Vertical Walls (the vertical surfaces directly above the wheels).
- Raising the walls increases the gap (more cards can pass)
- Lowering the walls decreases the gap (fewer cards can pass)
We refer to this adjustment as the Feed Height.
Cards Falling on Their Side in the Catch Tray
This is most often caused by shuffling too slowly.
Try this first:
- Turn the crank faster and smoother
If it still happens, raise the Feed Height slightly and test again.
Cards Aren’t Feeding In at All
The feed gap is set too low.
Fix: Raise the Feed Height.
A Second Card Starts to Feed, Then Gets Stuck
This is also caused by the feed gap being too low.
Fix: Raise the Feed Height.
Cards Feed In, but Turn or Go in at an Angle
This usually means the Vertical Walls are not set evenly from side to side.
Fix:
- Make sure both Vertical Walls are adjusted to the same height
- Feed the deck straight into the shuffler
Too Many Cards Are Feeding Through at Once
The Feed Height is set too high.
Fix: Lower the Feed Height slightly and test again.
Why 2–3 Cards at a Time Is Normal (and Good)
Seeing 2 or even 3 cards pass through at once is completely normal — and intentional.
A perfectly consistent 1-1-1-1 feed pattern is called a Faro shuffle, which is considered stacking the deck rather than properly randomizing it.
Urza’s Toolbox shufflers are designed to:
- Feed mostly 1–2 cards
- Occasionally feed 3 cards
- Create natural variation for better randomness
If you see only single cards or only large clumps, the Feed Height likely needs adjustment.
How to Adjust the Feed Height
The Feed Height is adjusted using the two Vertical Walls above the wheels.
Important: Only adjust the screws closest to the center of the shuffler, near the wheels. Some older models have extra screws that do not affect feed height.
Tools by production year:
- 2022–2023: 2mm hex key
- Early 2024: Torx T15
- Most 2024–2025: Small Phillips-head screwdriver
- Loosen the screw slightly (do not remove it)
- Slide the wall up to increase flow, or down to reduce it
- Gently tighten the screw (snug, not tight)
- Repeat on the other side
- Test and fine-tune
Important Safety Notes
- Do not overtighten screws — metal is stronger than plastic
- Do not use power tools
- Adjusting while cranking is fine
- If cards jam, reverse the crank and clear them — don’t force it
If a screw hole ever strips, stop and contact support.

The best thing you can send is a short video showing the feed area while you turn the crank. A video makes it incredibly easy for us to diagnose the issue.
