Steam Siege Frequently Asked Questions

How many cards are in Steam Siege?

Steam Siege contains 116 cards.

What is the Steam Siege booster box price?

The current booster box price for Steam Siege is £1007.33 (latest recorded reference via TCGInvest).

How do I build a Steam Siege master set?

Use the Steam Siege checklist to track owned and missing cards and the finishes listed for each card. Collectors often include reverse holos and other variants in a master set, but definitions differ. The 116-card catalogue count is not a verified count of every finish, stamp or promotional variant. Optional promos are tracked separately and do not affect standard set completion.

Is the Steam Siege Set Value the cost of a complete master set?

No. Set Value is the latest combined card price reference, not a quote for buying a complete Steam Siege master set. It does not guarantee every reverse holo, stamped card or optional promo is included. Check the individual printing, condition and observation date before comparing prices.
