Pros
-Really fun to play with
-Puts a lot of pressure
-Good roamer
-Can secure kills for your team

Cons
-Heavily dependant on the player landing Blitz's Grab
-Mana issues early game
-Long Cooldowns
-Not good in protecting an ally

Aftershock is a great way to increase your damage to the target and to increase your defenses after a successful hook or punch

Demolish speeds up plate destruction and first brick in the early game. In the late game, It helps at tower destruction

Bone Plating helps you against sudden bursts of damage

Unflinching can help you mitigate Blitz's slow after the cast of Overdrive

Legend: Tenacity Reduces the duration of all slows, including your own after Overdrive

Presence of Mind really helps Blitz's mana issues to a point that lane phase becomes a lot easier. This happens because you'll have more space to throw more Rocket Grabs due to the increase of mana after successful kills or assists

-Remember to buy Control Wards throughout the game
-Always try to help your midlane or even your toplane by ganking them (that's why you need to rush Mobility Boots)
-Avoid Grabbing tanks (specially mid-late game)
-Remember: your ultimate BREAKS shields
-Have fun!
