Strategy
Use Stifling Dagger to secure creep lasthits.
Try to get to 
Cornucopia early in tough lanes where you play passively and then get Power Treads to continue jungling faster. Send out extra regen if necessary to sustain and survive the lane.
Opponents are likely to have a lot of 
Magic Stick charges so take that into account when playing aggressively.
You can disjoint most projectile spells and ranged attacks with Blur.
When farming dangerous areas or stacks, consider using Blur.
Make sure to max Phantom Strike instead of stifling dagger post-laning phase for faster farming speed.
You typically want to focus on killing disabling supports and backliners at the start of the fight.
Check opponents' inventories for break effects and evasion-piercing items. Adjust playstyle and itemization accordingly.
Pick up 
Aghanim's Shard if you need the Break vs heroes like 
Timbersaw / 
Bristleback etc.
Counter Strategy
Phantom Assassin uses Stifling Dagger frequently to obtain lasthits. Buy Magic Stick and Magic Wand to get charges.
Armor items are good against Phantom Assassin as she is all about physical damage.
Cheap items that allow you to survive Phantom Assassin's Phantom Strike are Ghost Scepter, Glimmer Cape and Eul's Scepter.
Consider purchasing items that pierce through evasion, breaks passives or causes magical damage to counter Phantom Assassins innate passive evasion ability.
Blademail will be a big nuisance for Phantom Assassin unless she has Black King Bar.
Phantom Assassin is weak until she gets Black King Bar, try to smoke and gank her before that timing and set deep wards in the jungle to do so.
