Online Woes

I'm not sure why but I'm on a straight loss record for the Doomsday deck online.
Sure the hands have been rather bad but it's a little too bad for a bad record.

Last night I lost to UW counterbalance,
Game 1, I lost after getting my Doomsday countered post Rain of Filth as I Force of Willed the counterbalance.
I won 2 on Laboratory Maniac.
Game 3 I lost after my opponent had Jace in play and had a flusterstorm for my Unearth.

Round 2, I faced Painter
Game 1, I mulled to 5, keeping double Gitaxian Probe and tried to find lands. I ended up looking like I was playing Belcher.
Game 2, he had Grindstone out so I did not really want to Doomsday. I died to a bunch of creatures but was ultimately stopped by a Phyrexian Revoker naming Lion's Eye Diamond.

For a start, I am considering making an uncounterable pile with Cavern of Souls and using Chromatic Sphere to pick up the last draw which would win the game.
This whole "can't do well online" thing is worrying as I don't really know what to make out of it. Might be that I'm terrible at the deck, the deck is terrible or my luck is terrible. I suspect it might be the technicalities and the strategies that I am not too adept at but I hope that that is the case.
