Common questions

Getting started

How do I save and edit combos?

Open the Combo Builder, build your line, then hit Save. You can reopen saved combos from your dashboard and continue editing at any time.

Why can't I find a card in the search?

Try clearing filters (type/attribute/level) and searching by partial name. If it is still missing, switch to effect/description search—new releases can take a bit to appear as the catalogue syncs.

Sharing & exports

Can I share combos with friends?

Yes. Set the combo visibility to Public, then share the combo link or point friends to the Combo Gallery. You can also export a snapshot (PDF/image) from the builder; Excel downloads are available from the dashboard for saved combos.

How do I export a combo (PDF / image)?

In the builder, open the export menu and choose PDF, PNG, JPEG, or SVG. If export is disabled, sign in first—exports are tied to your account for reliable downloads.

How do I create an official decklist PDF?

Use the Decklist page to build your Main/Extra/Side counts, then click the Export / Print-ready (PDF) button. Your totals stay aligned with the official deck slots.

Dashboard & account

Where do I find my saved combos and downloads?

Head to your dashboard to view saved combos, manage visibility (public/private), and download exports like Excel when available.

Troubleshooting

The site feels slow or images do not load—what should I do?

First, refresh the page and try again. If card images are failing, it may be an upstream provider issue—check the API Status page for live health checks, then retry in a few minutes.

How do I report a bug or request a feature?

Email support@ygocombobuilder.com with steps to reproduce (what you clicked, expected vs. actual, and screenshots if possible). Feature requests are welcome—include your goal and any example combos/cards.
