Ok I use {Tezzeret agent of bolas} number 2 on {vault skirge}.....is it now a 5/5 flying lifelink or just a vanilla 5/5? I am trying to interpret the rulings but they are vague.
CbStrad is right. It would need the wording of {Turn to Frog} for it to lose abilities.
I thought so too thx guys
The first ruling on it states that only the power and toughness change.
