you have done the right steps for making an optimized 6-card HSR.

while using Success on Course Workers is more important than Pit Mechanic, i would encourage you to do both because they are close to having equal weight on the final soldier count of Speedster. you can use medals to buy Arcana Successions and also get them from AW chests. it's important to use succession at all times to get the most out of Speedster.
