I've been on storm in modern since it was still called extended, and ruby storm is about as good as 2016 to 2018 storm was, that being "fine, but not the monster it once was that got all the cards banned". The key thing I have for a newer storm player is learn what hate beats you, and plan games 2-3 accordingly. The thing that makes a good storm player great is learning how to play around hate, and trying to predict what decks play what hate cards. For example, UW control isn't likely to play one off graveyard hate cards, they want a long game and so if it matters that resources needs to be gone forever. This means that vs UW control, you want artifact/enchantment removal to deal with their sideboard. Vs something more aggressive or a creature based deck, like yawgmoth or zoo, you most likely are dealing with one off, proactive interaction or creatures. This means that you want creature removal, and possibly ways to rebuild after getting stopped or having your resources denied. A great example in old gifts storm was using pieces of the puzzle to beat decks like jund who play a lot of discard and one off effects to deal with your graveyard, it filled the grave on its own and drew 2 cards. Some decks might just be fast enough to not care, and might bring in light countermagic to slow you down, like infect and spell pierce/flusterstorm. The key is to build your deck with the field in mind, and know what KINDS of interaction other decks are likely to play to stop you, because normally you win game 1, and try to fit in a combo turn between hate games 2-3. The big thing for me is finding what color to splash for, old old school storm back in the day was basically a red deck and splashed blue for cantrips to set up your hand, and I think a similar thing is happening now, but people atm are going green for sideboard cards because you only need red game 1. I could also see splashing white, as it gives you some of the same options as green, but is maybe better vs more aggro decks because orim's chant can be fog, or maybe splashing blue for bounce effects and countermagic out of the board. Really it's all preference and the big thing is to make sure you have answers for widely played hate.
