If the value of cards is X when we only have a few thousand players, then what is the value of X when we have hundreds of thousands?

It's just a matter of time and smart marketing that'll see these card values increase over time.

Once the battles start we'll soon see what is needed to propel this game forward. Turn-based battles selecting cards randomly from your deck is probably the obvious path forward and would interest more strategic players in the long run.

As with limited cards, I suspect there will be quite a few mirror matches from the onset.

The real puzzle is working out which will be our 'Black Lotus' as that'll be the one to buy and HODL.

So HODL'ing is a sure bet either way at this stage.
