Looks cool (although I question the "relatively cheap" part, since it's possible to build a great ELO deck for around 20k.)
Kusuri is a pretty obvious choice for that 2* slot though, isn't she? She can provide a little bit of DR which gives her great synergy with the Frozn. She is also an excellent bait card and threatens KO with a furied Tsubame.
Oh, damn. 20k is a cheap deck? May try my hand at making one of them. Thanks for all the suggestions! I will try them all out until I find a playstyle which will work for me. Thanks all!
