Before I introduce you to this game, let me start off by saying:
This game is heavily Pay-To-Win. It's not like Elements where 5 bucks gets you a shard that you can get by grinding for a few minutes, it's like getting access to things Free-To-Play people can't get (Well, you can get them for placing high in PvP, but then you run into the P2W people... and it's not pretty, to say the least.) Knowing this, why should you play this game if you need to pay thousands of dollars? (Which should be donated here, BTW
) (Warning, this game is also highly rage-inducing with the amount of haxx that can go down. Seriously. It's more than Spike vs Fog Shield haxx)
You can still be competitive with a good deck and a few hours a week. It's very possible to beat higher leveled players if you have a focused deck and good strategy. Cough Rush Cough. If you haven't played this game before, give it a try. You might find it extremely boring, or maybe you'll find it fun!
