The best dTCG out there in my opinion. At least in content it has to offer. A free 10 hour campaign right now (that will get longer) that is like a tabletop RPG with tons of sweet encounters and mechanics.
3 sets out right now, with the 4th coming out in a week. Trading and auction house is very good. Tons of tournaments to enter similar to MTGO, though there are asynchrous tournaments like Hearthstone where you can pick up where you left off. Asynchrous Sealed which follows a format like Hearthstone arena and Asynchrous gauntlet which you play until you get 5 wins or 3 losses in best 2/3 matches. Draft is still a thing too, which obviously can't be asynchrous. Sets are balanced heavily on draft.
WHAT IS HEX? This article is good at explaining it. Better than I could for sure. www.hexprimal.com/an-in-depth-guide-to-hex-from-an-mtg-perspective/
Card value is good, but not too expensive. About half the cost of MTG. A Tier 1 deck will probably run you around $100 (or in the F2P side..A LOT OF GOLD) unless you want to play in blood (then it'll be $200 lol, blood has so many good legendaries).
There are budget options though. Especially aggro decks. Some control decks on the cheaper side though.
The cards in this game can be really interesting. There are gems which you can socket in cards to repurpose them for multiple decks. Here's one of the strongest socket cards right now:
and here is the list of gems:
Inspire is a mechanic where if a troop of a cost of equal or greater enters the board, it gains all abilities listed by the Inspire. So in this case, they gain all abilities the gems give Azurefate Sorceress
So a control sapphire deck may want to run the card with Quick (you can play the card on your opponents turn) so they can keep their resources open for counters. But the major gem slot is often different even among control decks. Wild Sapphire decks want the Spellshield(can't be targeted) for their boss troops to be hard to get rid of. Sapphire Blood decks want the mill gems so they can get the spiders (that they put in there) out of their opponents deck. Ruby control decks want the face burn on play so they can burst their opponent down when they get their combo pieces.
Less control decks might switch the sapphire Quick to flight. Flight/Spellshield can be a powerful combo for the more midrange decks.
Here is the Steam launch trailer
And here is the store page:
Core mechanics are very similar to MTG, but HEX won the lawsuit so who cares. Main differences can be outlined in this: http://www.hexprimal.com/hex-tcg-magic-the-gathering-clone-or-successor/
Though it's obviously a very biased article.
Also heres a thing trying to say why you should give HEX a chance:
A list of all decks that can win gauntlets and weekly tournaments: http://hexmeta.com/decks
www.fiveshards.com : Tons of articles and they host free weekly tournaments every Sat/Sun with prizes and door prizes. At the end of the month is a finisher tournament that invites the players with the best qualifying points.

A list of all the cards. Cards with the funny border on the left side are PVE only, and cards can have equipment which are also PVE only.

Some of my favorite cards:
--- > Puts this in your deck
It makes for a very powerful card if your opponent can't get it off the board quickly. Once it stacks up you'll be drawing Specter after Specter for some strong board presence.
A burn card that gets stronger as the game goes on.
Tunneling is a mechanic where you put the card face down for 2 and it comes up in a few turns (listed on the card..it's sorta like Morph) except it's a lot stronger and more interesting because the cards can have effects while face down. This one lets you see your opponents hand without them even knowing you can. Of course they can guess thats what it is, but decks running it run a lot of other threatening tunneling troops too.
A huge tempo card that demands to be answered.
More to be added later.
