I would use Spyke,Melanie, Lola, Elvis in halfdeck and mix it with something nice, for a mono its fine but you will severely lack versatility this week there is a bunch of soa and powerful ablity cards like spyke.
Dont even worry about ignorance my freind berzerk mono is very strong...ive reached 1300 a few times with it
Your deck is good
However Miho> Kusuri...I like her alot more than Spiaghi thnx to that 2 dmg
Kostner is a solid choice but i recommend Lola Noel...some people may disagree but many times she has been useful in stopping annoyances like Mona/Spiaghi/nellie...and used in conjunction with Melanie the tag team is a sight to see!!!!
