Akali's W?

use her w us a mobilet you can jump over walls with it, in lane use it as a gap closer/ escap or to dodge abilities and if you want you can trik players

You can use it to actually jump over the big mid lane walls. Which can really confuse players. You can use it in grass as the circular indicator won't show up seeming like she disappeared if they don't have vision in the grass. You can use it with jungle creeps to wait for your abilities to charge back up to attack. utilized often to Q wait for her next Q to come off cooldown ult auto Q auto for some heavy damage. It's very helpful though against auto attack junglers like yi or udyr. I'm not sure with guardian angel though if when you respawn if you'd be invisable as you spawned, but I'd be pretty confused xD.
