4.0
the fact it used a Chess AI to help you start understanding the game and will develop everytime you rank up
ranked match is also player vs bot (so there's no bad manners involve)
at the moment they're at set 4 forbidden with battle spirits collab
Gameplay is really interesting
the basic stuff is a mix of duel and mtg (both are the same game in the Japanese eye)
where you put mana with cards from hand/field.
instead of just either one
there's a mechanic called forces ( 2 Orb that you will be using)
grant a additional buff to your deck to further boost your deck power and how it works
it can be destroy thou so if you're deck is based on that one force you might want to defend it
then going first and second have its own advantage
first you can go aggressive which is normally a mono Red aggro style deck wincon
but going second you get a movement (action to put mana or take out a unit) so you play your stuff faster than your opp
overall in the end of the day you will learn how AI could beat you at playing your own deck
10/10 would get beaten again
