Door to nothingness

[adventus]

What's the name of that artifact (or is it a land) that you pay 5 and tap it for 1 mana of each color?

[BlackJester]

{Crystal Quarry}

[Artifex]

{Caged sun}, {Coalition Relic} or {Kaleidostone} can help you get there.

[Artifex]

{Channel the Suns} is good

... But already mentioned earlier. 😜
