Sometimes it is drawing the card to make it great, like Secure the Wastes
I know Geier Reach Sanitarium is generally cooler because it forces discard for your Megrim shenanigans, but for these kinds of forced draw decks, Mikokoro, Center of the Sea is just as good
As with most things though, it likely just comes down to supply and demand and there is plenty of the latter for this gold star card
This, in turn, leads to a lower barrier to entry for would-be tournament players, since the amazing lands they need for their deck are $5 a piece, instead of $15
The most dangerous thing for every card collector is water spills or high humidity conditions because they lead to the stripping away of the coating and colors
The little "AI" badge next to each field is the only visual reminder that I didn't type any of this
