{1}, {T}, Sacrifice Aureate Panorama: Search your library for a land card that could produce each color of mana, put it onto the battlefield, then shuffle.
2018-09-03
Aureate Panorama can fetch a land that has an ability that, if it resolved at this moment, could add mana of any color, or has one or more abilities that collectively add all five colors of mana. Do not consider any restrictions on the use of the mana or the activation of the ability, but do consider any replacement effects that would apply to that mana.
2018-09-03
The ability that adds mana does not have to be a mana ability. For example, Crumbling Vestige and Art Studio can be fetched.

If a land's ability depends on a choice that hasn't been made yet, such as Desert Palace or Nebula of Empty Gold, it can't be fetched.
2018-09-03
The ability considers the board state during the resolution of the fetch. For example, you can only fetch Chroma, the Faerie Circle during an opponent's turn, or Leyline Alignment Field while you have cards of all five colors in your graveyard, and you will be unable to find any lands if a Rylei Wakebreaker is on the battlefield.

Remember that the ability is checked while the card is still in your library. You won't be able to find a basic Forest even if you control Chromatic Lantern, and you won't be able to find anything if The Erased is on the battlefield.

Lands that provide access to five colors without explicitly adding mana, such as "Target land gains all basic land types," "{C} can be spent as though it were mana of any color," lands that create Treasure tokens, etc. can't be fetched.
