Amano artwork mention has me intrigued.
How many cards are playable?
I'm a long-time Magic: The Gathering player; like 15 years long-time. How does multiplayer work?
There are 215 cards normally obtainable, plus 20 or so Super Rare cards only available as prizes from tournaments. Playing in singleplayer, you can get cards from the first two sets (The Legend Begins and Otherworldly Visitor), and also cards from the third set (Legendary Dragons), but only from the 100 Man Battle. To get cards from the other sets, you have to either win Ranked matches (see below) or buy 24-card booster boxes from the Playstation Store for $4.99 each.
As for multiplayer, there are several options:
Ranked Play: Costs 1 ticket. You have 10 tickets at the start of the game. You can obtain more by either buying them from the Playstation Store (99 cents for 4, $4.99 for 21, etc) or by winning them in tournaments (more on that below). At the end of each Ranked match, you gain XP and get to pick a booster pack (containing one card) from one of the seven expansions. You get a booster whether you win or lose.
Tournament: Tournaments are free to play, however each tournament has a limited number of matches you can play (10 for single win, 5 for best of three). At the end of every tournament game, you get points. If you finish in the top 85% of the rankings, you get the runner-up prize (usually 5 tickets). If you finish in the top 40%, you get the grand prize (usually a Super Rare card, but sometimes something else, such as 7 tickets). You do not get booster packs after tournament games.
Friend Matches: Simply play against a friend. This is free, and no prizes, points, or XP are awarded at the end of the game.
I hope this was detailed enough for you.
Oh, also, the main thing to remember is
you CAN get everything in the game, including all cards and trophies, without buying any cards or tickets. It may be a little more difficult/time consuming, but it's completely possible.
