as the other of stated yes you could use the base set "Deadpool" for "Deadpool writes a scheme"
He does have the name "Deadpool" and will trigger any and all effects that use that name. For example in the scheme "Deadpool writes a scheme" he could be used as the Deadpool hero required.
however, the team affiliation is not deadpool its "Deadpool's Mercs for Money" so the base set Deadpool would not trigger any effect even though he is deadpool for "everybody hates deadpool" as it requires at least 1 mercs for money affiliation character for example:
Deadpool (mercs for money/lenedary: deadpool)
