This comes with 5 Pokmon TCG booster packs

I heard different WOTC employees imply that this is actually a Green effect all along and Urborg, Tomb of Yawgmoth was a color break which I strongly disagree with (tainting land is Black / Blue thing), and another WOTC employee say that yeah, it's originally Black's thing but we want to complete the cycle and we're just starting with Green is all

Which of these sets would you spring for, and what are you looking for in them

Im aware that this card technically has a black border, but Unfinity is, by all means, a silver bordered set and I refuse to treat it as anything else
