Rule 707.9c says
Some copy effects specifically state that they don’t copy certain characteristics and the affected objects instead retain their original values. Copy effects may also simply state that certain characteristics are not copied.
Are there any cards that apply this rule by making one object a copy of another object, except leaving some of the first object's characteristics unchanged?
Note: I am aware of cards like Dermotaxi and Lazav, the Multifarious with copy effects that explicitly modify the copy effect with characteristics that match the original object, but that is separately covered by rules 707.9a and b. It is also functionally different than what I am looking for: for example, if Mairsil, the Pretender exiles Lazav and activates its ability, its name will become "Lazav, the Multifarious" instead of staying as "Mairsil, the Pretender"
