I test with several different Level accounts
My experience with the previews is Quite to Opposite.
In the Prior Version 1.2.xxx
Previews were limited to 7 at a time.. and rotated out about every 10 minutes.
or you can Manually add one from the Store, but still limited to just 7 at a time.
Now In Version 2.x.xxx
I've had as many as 200 previews in the preview tab.
Can't say they got automatically replaced.
In the Queue View, yes the Auto Play keeps a selection of 10 waiting to be played
but in the Store on the Preview Tab, I have not yet discovered a limit.
If I go to the store and right click a card, and download the previews, it is added to the Previews Tab.
from there I can watch and rewatch any one of the previews.
Can't really speak for the TGIF events Other than if you are a New member and want to grow your collection,
the TGIF events are one of the better ways to do it.
True they Might Not be for the Discriminating Buyer, or the Full Collection Members.
The Newer Generation is Not so much Desktop users
they are More Handheld Device users.
The Mobile Platform, Which is 100% separate from the Desktop Platform
is More Attractive to the Handheld users.
One Subscription Unlocks EVERY single card available on the Platform.
even the VR180 video clips are included.
For the Members who want Both Desktop and Mobile
the two Higher Premium options are great values.
Pay for a monthly Reload of credits for the desktop, and get a free Mobile Subscription.
plus the Premium Discounts on the Desktop New card Releases.
Anyway, that my perspective.
We all see things from a different angle I guess.
The NFT's, well they filed a void that everyone kept asking for,
I want to trade in my unwanted cards, or let me Sell my cards to a different Member..
That is Exactly what the NFT cards allow you to do.
Buy a NFT, watch it, enjoy it, then you can trade / sell it.
Sometimes you can even sell it for a Profit.
But even if you can't make a profit on it, you get back a good portion of what you paid for it,
then can use that to offset the price on the Next NFT.
Unless you are a collector, then you end up keeping them.
Sell any Duplicates, and Keep the best one for yourself.
