A lot of combos can be done with pyke to secure a kill get a solo kill and just dominate a teamfight I can't go over every possible teamfight but with these basic combos you should get the hang of most combos and what to do in teamfights.

Your Q E combo will be used the most in lane normally you will land a hook and e backwards towards your tower to be safe or forward if they are low and you can be aggressive.

The E W is just e foward and use w to catch as many peple as you can sometimes you can pair this with ghostblade active to catch out 3 or more in a teamfight

e q aa r Sipmle oneshot combo on an adc or squishy support if you land e it becomes a walk in the park combo sometimes you dont even need to ult.

Triangle combo This is the most mechanical and advanced combo
First, you want to have 3 people standing in a triangle a bit spread out then you will e 2 ult the other and flash to stun all 3 it takes a lot of practice in practice tool but pays off huge when you get this off in a teamfight/ skirmish and will normally result in 3 people dying.
