I think the best thing you can do to this deck is replace a Roc with Jean Gray(Phoenix) plus you might want to add a life absorbing machine so you can have something to regain LP.

B grade deck.

Yeah phoenix might be useful in fact im considering it, however i preffer to have 1 tribute mosters Roc has the same attack as phoenix, also i feel that there isnt any need to add massive spell/trap destruction since harpie´s hunting ground is there i also have heavy storm and mst.

and what do you mean by adding life absorbing machine? i dont have any card that makes me pay LP for activation or cost.

thanks for your suggestion

yes you do you have mirror walls, if you want to keep them active you pay 2000 lp. I'd say replace the harpie 1's and 2 with 3x Cyber harpie, they have a lot more punch on their own then the 1 or 2
