Dude! Don't let those Djinns spoil your soul.
I don't play with Djinn Bilkja myself... but I've been absolutely stomped by him when he's paired with Obsidian. Honestly, the ruleset where you're limited to 4 Mana cards or less, I can't beat a Obsidian magic deck.

Haha, your opening paragraph is pretty much identical to how I felt last season. I could just not get it done. Oooof!

You're right about the win/loss ratio. 1 is 50/50.
I wouldn't put too much stock in this metric though... if you didn't play at all the whole season and then went nuts in the last 12 hours you'd probably have an amazing win/loss ratio.
