Expansion symbol

The expansion symbol is a small icon found on the right side of the middle line or type line on a Magic: The Gathering card and is a characteristic of that card. If a card is copied, the copy will keep its original expansion symbol.
==Description==
An expansion symbol indicates what expansion a card belongs to. Starting with Sixth Edition (1999), every Core Set also used an expansion symbol.
Expansion symbols were black-and-white through the Stronghold (1998) expansion. Since the Exodus (1998) expansion, expansion symbols have incorporated colors to identify the rarity of each card: common cards have black symbols, uncommon cards have silver or black-to-white fade symbols, and rare cards have gold symbols. The fourth rarity, mythic rare, was added with Shards of Alara (2008), its color being a red-orange gradient.
Time Spiral (2006) had a unique purple symbol to represent the 121 bonus timeshifted cards in the set. This color scheme was reused in Time Spiral Remastered (2020) for their modern-to-old frame timeshifted sheet.
The Chronicles expansion consists entirely of white-bordered reprints. It is unusual because it does not have its own expansion symbol and instead uses the expansion symbols of the cards' home expansions.
Although the Mirrodin Pure set never came into being, its expansion symbol has the same status as the other expansion symbols.
==Rules==
==Requirements==
A designer must infuse recognizable fantasy flavor into an expansion symbol while also fulfilling these tough requirements:
*Hold up at about 4 millimeters high and 8 millimeters wide.
*Can't look too much like any other expansion or game symbol. 
*Has to work in solid black, as well as in silver, gold, and orange-red.
*Has to be a scalable, vector-based design (because sometimes it will also be seen really big).
==Expansion symbols matter==
Three tournament-legal expansion hosers used to refer to set symbols. Because modern rules states that cards with the same name are identical, the aforementioned hosers received an errata to refer to cards' original expansions. 
* hoses cards originally printed in Homelands.
* hoses cards originally printed in Arabian Nights
* hoses cards originally printed in Antiquities
Non-black-bordered cards are allowed to care about set symbols. Acorn cards that do so are as follows:
*<c>Greater Morphling</c>: for , this card's expansion symbol becomes the symbol of its controller's choice until end of turn.
*<c>Symbol Status</c> puts a 1/1 colorless Expansion-Symbol creature token into play for each different expansion symbol among permanents its controller's control.
*<c>World-Bottling Kit</c> lets its controller choose a Magic set for . Remove from the game all permanents with that set's expansion symbol except for basic lands.
*: Whenever you cast a spell, you may create a Treasure token if that spell doesn’t share an expansion symbol with a permanent you control or a card in your graveyard.
One Mystery Booster 2 test card cares about expansion symbols:
*. Your starting deck contains no cards with a silver, gold, orange, or purple expansion symbol.
