This extra utility takes an already great token card to dizzying new heights
Something you've never been asked to do
If Gobland gains flash, or you have the ability to play Gobland as though it had flash (due to Teferi, Druid of Argoth, for example), you can ignore the normal timing rules for when during your turn you can play a land, but not any other restrictions
But for Constructed, it's harder to gauge
Gone is the silver border, instead Unfinity cards are in black border so that some are legal in eternal formats
If all this card did was just read: "Lands you control have 'Tap: make a mana of any color," it would hit a few slots back on the next list, but it breaks defensively minded brews since they aren't punished for not using their mana each turn since they can just tap it for Treasures
