The WOTC page for 5-0 decklists is:
https://magic.wizards.com/en/content/deck-lists-magic-online-products-game-info

Also, MTGGoldfish scrapes the site and puts them onto their Vintage Results page:
https://www.mtggoldfish.com/tournaments/vintage#online

The MTGGoldfish site is much easier to use (the filtering/sorting on the WOTC site is broken) and they also include the Weekly Challenge lists. This could save @joshuabrooks the trouble.
