Well it started as a troll attempt. But really, looking through the platinum rankings one thing immediatelly shows: many decks are old, and lost much hp. So I build a deck for that:

The idea behind it is easy: getting EM on low hp abbominations. Decks of 8+ days are guaranteed victory, almost guaranteed EM (guaranteed 1 turn). 7 Days is also almost always a victory.. And 6 day old decks are worth trying if they didn't invest in health a lot of points. Anything else = skip.
A quick view of the highscores shows that about 1/3rd is 7+ days old (heck probably even more).. For easiness sake say it's 1/4th, of which you get EM half the time.
That means an average game you earn
( 3/4) * -15 + 1/8*160 + 1/8*340 = 51.2 coins.
Chance on special spin is (1/4) ^3 = 1/256.
Well special spin chance is low, but looking at the profit, and considering that each game will only be 1, maybe 2 rounds. Is this a troll deck?
