Order of Move Success Checks needs to be modernized

"We can use this data to determine, for example, what effects will and won't change a user's typing with Libero, where PP is deducted from the move, where Protect stops an effect before revealing an ability/item, what checks are blocked before/after Substitute, and so on."

• [x] Compile data into the table
• [x] Figure out the execution order of the vanilla functions
• [x] Propose solution
• [ ] Implement solution

	Aromatherapy while no party Pokemon have status conditions	But it failed!	No	Heals status from left slot -> right slot (does not fail from left -> right)	Text: "A soothing aroma wafted through the area!" Aromatherapy does not cure the status when an ally is behind a Substitute or the ally has Sap Sipper. It has no other means of failing on the user except by not having a status condition curable by Aromatherapy. Aromatherapy never doubles Stomping Tantrum, despite both Sap Sipper and Substitute independently causing Stomping Tantrum to double in non-Aromatherapy situations. We also know that Aromatherapy heals statuses normally from left -> right. But if you use left slot Aromatherapy with Sap Sipper in the right slot, it plays Sap Sipper, then but it failed. So I think Aromatherapy without status conditions is a post-Sub failure, and that the game would have doubled ST on Aromatherapy failing vs. Sap Sipper / Sub; however, because it will always either do a non-ST fail (user lacks status condition) or a success (user has status condition) we can't know for sure.
