Added a further reference to the artwork of cards that feature (or do not feature) spell counters
A Spell Counter itself does nothing. Certain cards require Spell Counters to use their effects. When a card with Spell Counters on it are flipped face down, all of their Spell Counters are removed.
1 or more [[Pitch-Black Power Stone]]-esque orbs are usually on the clothing or accessories of the monsters that use them. In a thematic sense, they might be the spell counters, or at least containers for them. These are usually cards whose effects involve Spell Counters in some way, like [[Skilled Dark Magician]]. However, some cards like [[Old Vindictive Magician]] feature Spell Counters in their artwork when their effects have nothing to do with them. Other cards, like [[Dark Red Enchanter]] feature no Spell Counters when their effects rely on them.
Spell Counters are usually centered around [[Spellcaster]]-[[Type]] monsters. The [[Structure Deck]]s [[Structure Deck 6: Spellcaster's Judgment|Spellcaster's Judgment]] and [[Structure Deck: Spellcaster's Command|Spellcaster's Command]] contain a number of Spell Counter related cards.
