Bleeding and vitality are both easier because you play double. Harmony see like it should but it actually doesn't work as well because if you draw the wrong race at the wrong timr you lose the ability to trigger it. Shield and poison are both a lot faster but not nearly as fast as assimilate.
I play on PS4 so not easily. Basically load up on spies and assimilate. Dutchess informant is great for this. Also their is a 9 provisions card that allows you to create a 1 power bronze from your deck. If you still have trouble let me know and I will provide more specifics.
Also use the leader refresh card and Anna, she can get you 3 extra cards from opponents deck, causes tons of pings and wins matches.
Operator is also very useful for getting Ducal Guard or Imperial Diviner on the opponents field and graveyard. With Duchess you can then get extra copies and resurrect them later on with Experimental Remedy.
