Questions gathered since september!

Hi there, I missed to read the forum since september, so I lost some news and I also have some questions to upgrade myself!
I would remember I don't speak english so well and it is the reason if maybe some questions of mine would be already ansered, in that case if you would link the topic I would try to read there, or if you want to teach with your words it is good too
So: back in my time you where all drained with Magic 2014, I would like to know if there is a link where I could download it for free (There are more versions as Theta, Skidrow? There are differences I would know before to chose a version? The system requirements are the same of 2013?)
Then I would to ask about the Xbox 360: I have the games of DotP from 2010 since 2014, but I can't found the DLC, could someone link where I could find them please?
Talking about Xbox 360: it is possible to apply the mods also there? I would love it!!!
The last topic of my questions is about the modding of dotp 2013 and 2014 too.
There are difference between the two games for that I should prefer to mod one and not the other? For example if one is more simple than the other, or if one allows the online game and the other doesn't.
Other difference: there are more already coded card for the 2013 or 2014? There are the better tutorial and tools for the 2013 or 2014?
Then I would like to answer which tools, tutorials, and already coded cards and decks, but first I should know if I have to download the 2013 or 2014
I would like to thank, thank, THANK you a lot if you read since there, and I would love you if you try to answer to my questions
