You're welcome, hope this vid really helped you.

I understand where you're coming from. This is still RNG (sheer luck) after all, we cannot escape that. We're just cutting our losses by not making our (esp. two) best pieces sacrificed with one trash piece and contaminate it. You have no idea how many fall victim to that - they thought more instances of their preferred color = more chances of winning, even if all 4 colors are present at the synthesis roulette. It's not! Someone who can try this can at least guarantee saving best resources for more attempts to try, even if it's still a gamble in the end. That's the only calculated part of this "guide". As anecdotal evidence, my Fake War Mage account is currently at 15 Fire pieces out of a total of 35 single blocks I have. It still can be outsmarted somehow, even if in retrospect, I only "won" Fire 43% of the time (15/35). TL;DR: Yea it's still RNG, but you'll learn how to save here. Don't knock it until you try it!
