Skill Overview
Android 18's Skill Tree primarily focuses on expanding her tools for close-range offense. Her Battle Skills grant her new tools for conducting and capitalising on mixups and okizeme, her Passive Skills further aid her offensive capacity with buffs to her damage and movement, and her System Skills giver her extra help in closing the gap. Because her Skill Tree is so singularly focused on her close-range tools, inheriting skills that help her play at further distances is usually considered a must for Android 18.

Skill Recommendations
Skill Tree
ATK Up > Surround Attack > Rising Sun > Impact Up > Armor Strike / Shield Sprint
ATK Up is recommended here because 18's aggressive playstyle means she builds a lot of meter, giving her space to opt for more damage.
Surround Attack is a good option not just because it gives 18 a tricky movement tool, but also because it also gives her access to 
Rising Sun, which can turn any ground confirm into a juggle.- While
Impact Up and 
Ground Speed Up are both equally viable, Impact Up is usually the preferred option, as it increases the launch height on Rising Sun, allowing for more consistent and damaging combos in a greater number of situations. 
Armor Strike and 
Shield Sprint are both great for 18, as they grant some extra utility to her offensive approach tools. 
Assault Style is more situational due to it not coming into play until 35% life, but it can't hurt if you feel you need an extra comeback factor. Pick what you like the most.
Inherited Skills
Battle Skill: 
Flex Laser / 
G. Slicer
It's up to preference, but projectiles are good for 18, who doesn't have much in the way of those otherwise.
System Skill: Armor Strike / Shield Sprint
Take whichever of the two you didn't take on your skill tree. If you took Assault Style, pick one based on preference.
