Entropy Well.. Back when i started, I chose water as my first element and loved it, sporting a chrysaora spam deck. Later on, after getting two cards upgraded (My arsenic/ice shield), i wanted to try T50 and up and found out.. this deck didn't quite cut it..
Few account resets later and forum foraging, I stumbled across my next deck. A Mono-Aether Dragon rush deck. Loved it so much, i started to upgrade it, farming T50 like crazy, even the occasional AI5. Finally, I got brave and wanted to take the final step, into the dreaded FG games. Again, I faced the same problem.. False Gods > That deck.
Debating on what to try.. I finally settled on Scaredgirl's "ALMOST" un-upgraded FG deck (
http://elementscommunity.org/forum/index.php/topic,1615.0.html).. And within a few games.. My first FG victory! I was ecstatic! After that more wins followed, upgraded card won after another, and more upgrades were made, to the point of nearly fully upgrading(Maybe I did fully upgrade, I can't quite remember..) But.. i noticed one flaw.. I was often just.. sitting there, waiting for my few QT's that I'd draw, not giving me enough quanta, so my deck searching began, once again..
I hadn't really found any deck to my liking, the majority of them being time-bows or something off the wall that would have taken quite a long time to make/test. (At the time I didn't know about the trainer) So at this time hope had been released, and noticed that "Hope+RoL+Fractal" decks were all the rage, and decided.. Hey, why not. -joins the crowd- Selling off my SG deck, and upgrading the necessities of it to make it "work". To my unfortunate realization.. It.. Didn't work very well (For me, I know the deck itself, when built right and fully upgraded, it kicks major butt), in fact, I was losing MORE, even vs FG's I should've beaten with ease.. Back to the drawing board...
Having to nearly start from scratch and doing some searching for both a new deck to make some money and a new FG deck, I found SG's Fast draw unupped pillarless AI3 grinder (

http://elementscommunity.org/forum/index.php/topic,4212.0.html), both decks that I <33 to this day. This was my first brush with nova.. and I started to take a liking to it. (Main reason I chose Yaladilae's deck, was to try out Snovas) Many.. Many.. MANY Ai3/Pvp 1 matches later.. I made Yaladilae's deck with a few alterations of course. It proved to increase my FG win ratio by a good 15%! (A guess-timate, don't take it at face-value) It was at this time that I fell in love with Supernova. It was so successful, I was able to create an alteration of Terroking's Speed + Rainbow = Win (
http://elementscommunity.org/forum/index.php/topic,5786.0.html) and a standard graboid rush (both fully upgraded) just for kicks within a month-ish of playing with the deck!
So to close this long, drawn out story, Entropy is my favorite element because of one card.. Nova/Supernova. It is so versatile, and with a splash of entropy and some novas, you can create one hell of a rainbow.. anything! I wouldn't be where I am today without the wonders of Nova and Supernova. Yes, I understand there are other awesome Entropy cards, but that's the one that makes me say,"Entropy is my main/favorite element"
