Eyrik could be changed to Ambre use her with Copper and your opponnent will give you the victory

You have an attack based deck not a power based deck and while Ambre would be a great addition i suggest you use Hugo he's cheaper and in some cases better

The reason I like Ambre better is overall she almost adds three attack per pill used.
For Eg. I'll use a card that has no manipulation to make this easier to understand
Tsubame *4 pills(Including free pill) say equals 28
Ambre+ Tsubame * 4 pills =40
With that said Hugo work on all turns so can be better but depends on your play style.
But With Eyrik it is a differrent story he minuses the opponnents power which makes you use less pills and with the need to pill from the atack manipultion so he may still be a choice

Hope this helped
