Nostalgia

Nostalgia was a deckbuilding mechanic designed for Time Spiral. It was never released.
== Description ==
The idea was the card say that if it was in your deck, then you were allowed to have up to four copies of a card from the past in your deck even if that card wasn't normally legal in Standard. Understanding that those cards might be broken cards, Mark Rosewater found six subsets of past cards, one for each color and one artifact, that could work.
When the mechanic threatened to make deckbuilding legality too complex, Rosewater converted into the un-keyworded gatekeeping mechanic, where you could copy, or play token copies of Vintage-legal cards of the given subsets. This version was also eventually nixed.
The six designed cards were:
Nostalgic Veteran Creature Soldier2/3VigilanceNostalgic – 2/3 (As long as this card is in your deck, you may have up to four copies of any 2/3 creature legal in Vintage.)
Nostalgic Wizard Creature Human Wizard1/2: Draw a card, then discard a card.Nostalgic – Wizard (As long as this card is in your deck, you may have up to four copies of any Wizard legal in Vintage.)
