I have been playing a bit of M:tG-PQ (punctuation adventure). Puzzle Quest is basically good match-3 gameplay, even the version drowned in F2P2W, and this is another entertaining implementation. Matching gets you mana, mana summons monsters or casts spells, knock out your opponent to win. Pretty standard.
It is more Magic-themed than an implementation of magic. The five colors of mana exist, and they influence what spells go with your planeswalker and how much mana you get for matches. Any mana powers your cards, you just get more for certain colors. Planeswalker abilities exist, enchantments go on gems and last until they are matched X times, and some monsters block but most just attack your opponent. The elements that are borrowed from Magic seems fairly deft.
It is a F2P game. It is hard to fault something card game-based for selling cards. That seems almost entirely in the RMT currency, with the free currency being used to level up planeswalkers. I have no idea what level of P2W exists in the (standard asynchronous) PvP world there; I do not expect to play that far.
One of my main impressions is how random the game is, between cards and gems. I have several times lost a fight, restarted it, and won it without taking damage. Some games I cannot summon a monster, others I completely control the board, even when that “other” is against the same opponent. Maybe that goes down at higher levels, when higher hit points and better customization options mean it averages out, but then maybe you just get bigger, faster snowballs at higher levels. I do not expect to play that far.
Briefly entertaining, and a good commercial idea, but I cannot say that I can recommend it strongly.
