Its not that simple as you described:
Fact 1: Majority of land will lay vacant.
Fact 2: Ability to get cards to work on Land is a 2Q 2023 activity. Although land claim will release earlier, likely Christmas 2022.
Fact 3: Rebellion will be released prior to land-card staking, thereby increasing additional 15M packs
Players will have to weigh, which is more profitable, staking card on land or playing them. I am sure answer will vary from person to person based on their deck, goal, investment etc.
Good thing, this add depth to the game.
It never is :)
I don't think they should release Rebellion until there has been some experience with Land, as I reckon it would make the FOMO on a new set far greater, putting more pressure on buying packs, but also give the feedback on how Land operates, meaning the prices of existing cards will be affected too.
Yes, I am sure. There will be very few who will be able to fill their land, let alone with what kinds of cards optimize it. It will be interesting to see for example, whether it is better to use 2 plots with gold level cards or 1 plot with max.
This is as it should be - there should be the tension and inability to be able to do both (all) things simultaneously.
