That is the planeswalker games. There is alos MGT online which is just the game in virtual form. All cards, tournments, and various levels of play. I actually just recently started playing and its pretty nice. It costs 9.99 and they give you several hundred cards with the start and you can build decks how you want them. The decks are also seperated by editions and various other formats. You can even transfer your physical cards over to digital if you want, but you have to mail them off too Wizards of the coast. You can also transfer your digital cards to physical card, IF they're from recent editions up to 3 years back. SO yes there is deck building as long as your play MGT online instead of plainswalker games. Its actually kinda nice since you can easily find people to play with.
