Thank you for your suggestion I will try it in a short time

Building Infinity Edge right after Trinity Force is pretty precious as you're investing so much into two of the most expensive items in the game. You cann follow up with BT or BorK as the second item your consider LW in certain games.
Rather skip Warlord instead of Devastating Strikes because DS provides the two kinds of penetration Corki benefits from plus this mastery is worth having at every stage of the game whereas Warlord just scales a tiny bit.
