Collectible Card Game Headquarters

So I made a Deadpool card. Here are all of his abilities:

You may tap lands you don't control for mana to cast Deadpool.
Mana can be spent to cast Deadpool as though it were mana of any color.
Deadpool can be played from your graveyard.\nWhile you're searching your library, you may cast Deadpool from your library.
Flash
: Regenerate Deadpool

I Finished Scripting all of the abilities except the top 2. These ones don't already exist so I'm not sure how to go about making these work. Please Help!

Thanks in advance.
