Thanks for the reply, @arkasz.

Since there is much that is still speculation, it is hard to say how much of the crafting gameplay a non-landholder will be able to participate in. There has to be something that is specific to lands though, or there would be no point in owning them.

In particular though I would like to speak to your last point as I do not think your example is a valid comparison. Byzantine Kitty is a specific card, so the valid comparison would be to a specific type of legendary land. Think instead if they said that from now on there would be no more Summoner cards minted. Everyone who didn't already have the summoners they need (including all new players) would have to rent them. You could still say that anyone could take part in all parts of the game just by renting their summoners, but would it be as much fun for those who had to rent as it was for those who were holding all the good cards? Would anyone who wanted to play be able to find summoners to rent that they could afford?

This is in fact a general concern that I have about land in blockchain games. The focus seems to be more on making sure the land value goes up rapidly rather than making the associated gameplay available to the widest number of players.
