What's the best/most played TCG on PC?

Whats a TCG?

Guessing Magic or Hearthstone...

MTGO

I'd also say Mtg or Hearthstone. I'm amazed that MTG is so popular, I played back when Ice Age came out and stopped in about 2001, but it's still going strong.

I played in the Hearthstone closed beta and liked it though, much more than Mtg.

defently hearthstone is the most popular atm.

I'd sign up for MTG online. You still have to purchase the cards but if you go to mtgotraders.com you can get them for real cheap. The cards are much cheaper than the paper ones.

Oh I got this. As a fellow TCG lover here we go.
You want high value animation, simple rules, great replayibility, a can you catch them all type card game?
-Hearthstone. (cons:Low variety, endgame decks are all identical with no counters)
You want more complicated and varied decks, less animation but more serious artwork, more card types than spell/creature/trap?
-Might and magic:Duel of champions (cons: People who don't get deep feel cards are hard to obtain, but I own 1.3k cards in one month as a free to play player).
You don't care about multiplayer or collecting? You just want the high animation + card complexity? No booster packs =(?
-Magic the gathering (any of them). (cons: No real expansions, just a newer version with a set of cards you can make a deck from)
You want a game different from the rest, a card game almost purely dependent on luck and hate?
-Solforge (Cons: Dying game with pure luck determining the winner)
Oh you want PVE only? Are you not mentally ready for PVP? but want complexity in the cards?
-Hex TCG (Cons:still in closed beta, every cads has a pvp and pve stat/ability, currently very overpowered cards are for closed beta exclusives)
Enjoy!

Just a heads up. Are you really looking for a TCG or are you fine with a CCG?

• TCG = Trading Card Game
• CCG = Collectible Card Game

Note, that some games can be in the two genre but a difference of the two is that CCGs dont' have trading features. *Magic: The Gathering Online is a TCG and a CCG while Hearthstone is strictly a CCG.

EDIT: Looks like you already know :p It took a while to write this because of a bathroom break. lol

On the internet would be Hearthstone but in real life it's yugioh

I kinda like Scrolls but it isn't very popular due to the cost.

What is the cost associated with Hearthstone? A friend and I play MTG occasionally and I'm curious if it's worth check out Hearthstone. I'm not interested if it's an endless money pit though.

There aren't too many tcgs for PC. The only ones I remember that have trading + have a decent playbase are Hex and Infinity Wars. MTG probably has a decent playbase online as well

I played Eredan a couple of years ago, I played for like 2 years and I only got bored because that's me, I get bored of TCGs after a while, but it's a really cool game actually.

Steam trading card game

If you get this, enter in any scheduled tournaments possible. It is the best way to get card packs.
