Two parts. 1: With "Cyber Harpie Lady", "Harpie girl", "Harpie Lady 1", Harpie's pet baby dragon", and "Rising Air Current" on the feild. Harpie's pet baby dragon goes from 1200 to 2000 (1200+300+500=2000), will his second effect kick in on his 1200 and make him a 2400 then get the 300+500 or will he get that first then double his attack making him a 4000 ((1200+300+500)x2=4000).

2) "Rallis the Star Bird" If he was to battle a 1300 4 star would he go from a 800 to a 1600 during the two monsters fighting and win, or does it only kick in if he does damage, and if I skip my battle phase (end it during main phase 1) and go into it my next turn would he come back?
