It's me here, Robsta43. Apparently I should introduce myself or something.
I believe I found out about Elements from browsing Addictinggames.com something like 10 years ago.
I tend to rotate around the games that I like to play a lot, for elements sometimes I forget about it for years at a time, then remember it and about how good it is, and come back for a few more months of play.
Currently sitting at level 67, around 2000 cards, not going to count the number of upgraded cards right now, but it's multiple-hundred.
For all I know, many of my strategies could be years out of date, and a few of my pvp decks are unique to me.
I still think Arena is a cool new idea in elements and well implemented.
