Before I made a comment, this is meant to be a fun FG deck, away from the rainbow and RoL hope boring everyday electum grinding hehe
I did have a few terrible draws before, but rarely to occasion
The thing there is so little bone tower is because if you draw 1 or 2 early, you get to stockpile, almost all games i played, i have over 30+ stockpile death quanta before I draw the last card (involving the use of a 3 or 4 hourglass chain drawing)
Eldinis is a big exception, because people think he is easy, but he is not that easy in some cases, since rediculous healing and immarterial things dont drown, which hurts. He heal too much, so building up like 80 or so poison to start damage him will take forever... He might not be hard, but he definitely is a slow kill
Prehaps you could try adding a few more bone tower, but that means you have less chance to have 1-2 hourglass in opening hand, which could really hurt
