I might go with 2 x Tar Creeper, King Mukla and Captain greenskin as a replacement for GI and BK at the start. There are not many good options around though.

To be able to even survive game into your combo turn you have to use some of your valuable resources such as eviscerates to do OTK otherwise you have to pull perfect combo such as atleast 3 malygos on board. It is fun but too inconsistent unfortunately

As a huge fan of old Miracle and Malygos rogue with Auctioneers I have also tried a variant of Malygos rogue with Kobold deathrattle and I must say it is horible in aggro meta and the combo is not consistent enough. Deck misses counterfeit coins and Pillagers in my opinion.

I have reached Legend rank today with Odd rogue deck. I must say it is very well positioned in the current meta atleast between 5-1 ranks. I have met mainly Zoo warlock,, Shudderwock shaman, Tempo mage and Hunter and some druids. Almost no warrior, paladin or priests.
