Borderless and showcase frames of Stronghold / Mox Diamond still need the STH line; a fancy frame is not a different set by itself. Also watch foil vs nonfoil: sheen does not change which set Stronghold is.
Confirm after the icon
For Stronghold, prioritize edition/authenticity cues over rarity-color habits, then compare comps for the exact printing of Stronghold / Mox Diamond — not a generic name search.
How to identify Stronghold cards
- 1
Locate the Stronghold set mark (STH) before you trust the card name — reprints reuse names across products.
- 2
Do not read rarity from symbol color on this pre-Exodus printing; use edition context instead.
- 3
Verify STH on the bottom line; listings that only show the card name are where Stronghold get mixed with siblings.
- 4
If icon and STH still disagree with a marketplace title, scan with Tappr rather than guessing from art.
Rarity by symbol color
Pre-Exodus printing (1998): expansion symbols were generally monochrome and did not encode rarity by color. Identify Stronghold with edition cues and set context — not black/silver/gold folklore borrowed from later sets.
Legend shows the modern post-Exodus palette. Pre-Exodus sets and special rarities (for example Time Spiral purple timeshifted) follow the rarity reading above — not this swatch row alone.
