I tried to make one in trainer but it ends up with SO MANY bad draws and doesn't EM much.
SODs don't make bad draws, you can play them with every element?
Well, your main problem is your restriction on deckbuilding. The SoD is not a Level 3 card because damage is all that matters against Lvl3s. The SoDs don't even help for EMing.
I guess you can throw some of them into a Life rush...
True, i could aim for level 5, too. I am looking for the best score per time deck.
Best results i could get is to build a large entropy rainbow with 2 added time towers and 4 hourglasses. Does the job and i em the level 5 like everytime, which nets 140 electrum. But its way too slow, i am better of grinding top50 with my speed rainbow.
