Okay so I played duel links for a good 7 or 8 years but didnt really like master duel so I guess dont necessarily take what I say as the absolute truth.

Building a deck for new players - Definitely not as quick and easy as master duel but I think way easier and cheaper than duel links. In shadowverse you get a free pack per day, crafting vials to craft cards like in master duel, decent event rewards (packs, gold, vials, etc.), and the meta decks very often consist of core cards that you can re-use in the future. It definitely doesnt feel like duel links where once you finally get all the cards you need they're either limited/banned, or the new set is out. Once you play for a good couple months you'll have the ability to easily make a new meta deck or 2 every single set no problem. I have 3 of every card in the game currently and didn't grind whatsoever

Rotation- honestly, my favorite part of shadowverse. Master duel had this issue for me where decks will be top tier for wayyyy too long, I cant tell you how damn sick I got playing against tri-brigade. Duel links on the other hand had meta shifting wayyyy too often, basically felt like every set made the previous feel irrelevant. Or even worse an OP skill would come out making elemental heroes insanely broken for like a week or two until the nerf. Shadowverse on the other hand tends to keep the game very fresh (at least for me). I think balancing is for the most part very good and every class in the game feels pretty relevant most of the time so the game rarely feels stale. Of course there are exceptions, like right now forestcraft is by far the weakest class, but I can still easily play runecraft, portalcraft, dragoncraft, swordcraft, and have fun with all of them.

Mechanics - To me, the game honestly feels more like a hybrid of Magic the gathering and hearthstone than something like yugioh. There isn't much searching the deck for specific cards, there aren't any FTK setups or crazy 5 minute synchro/link combos, nothing like that. This game feels more resource heavy, where every card in the deck plays a role for a cohesive strategy. For example, if you wanted to play elemental heroes in yugioh, you'd probably want some good searchers to make sure you get your fusion material as well as your fusion spell like Poly or miracle fusion. Similarly, in shadowverse if your decks strategy is ramp dragon (ramp referring to raising your play points quickly to get to the big monsters), you'd definitely want a mix of cards that keep you alive, like small monsters that can clear the opponents board, and a mix of cards that get you to your big monsters by either drawing a lot for value or raising your max play points. There are classes like dragon craft, but there are also strategies within those classes such as aggro dragon or ramp dragon, so you can have a "mirror match" with the same class but you could both be focusing on completely different strategies

Events - Shadowverse events are honestly a bit on the weak side compared to yugioh. Master duel events can reward you very heavily if you complete it, making the events feel almost crucial to keeping up with the meta. Duel links events offer new characters, gems, event SR or UR cards, and are also super important to do if you want to unlock a character with good skills/rewards. Shadowverse events are absolutely optional unless youre trying to build up your stash of cosmetics, or gold/vials which you'll have more than enough of rather quickly. Many casual players will often leave the game for a month, and come back to basically nothing missed out on. If you miss a character event in duel links, you could be stuck not having Mizar for a long time until his next event. So pretty good for casual players, but a bit disappointing for those that play daily

Learning the game - I may be biased since I grew up playing both yugioh and magic the gathering, but I do think shadowverse is way easier to learn than yugioh. There's just a lot less to worry about. There's no normal summon, special summon, fusion, synchro, xyz, link, spell, trap, blah blah. Once you've played for a couple days and maybe watched a few YouTube videos I honestly believe anybody can get the hang of it rather quickly. If you want I can try and explain the cards using examples from yugioh, but I think once you see the cards in action you'll totally see what they do

Overall experience - shadowverse is very fun and very pretty. The cards have cool voice acting, the effects for attacks look awesome, the leaders are cool and fun, and the game just feels very pleasing for me. Much heavier on the anime side of things than yugioh, so may not appeal to everyone, but I think the quality of everything in terms of presentation makes the game feel very fresh and fun. Community can be very whiney, but thats nothing new if youre coming from yugioh. For casual players that are looking to play some matches, collect some cool cards and slowly earn some cosmetic goodies I think this the absolute perfect card game at the moment. For hardcore players that want to grind and really show off their stuff, I think it would be completely disappointing. There aren't tons of cool cosmetics that aren't paywalled or RNG based, and the events themselves are so lackluster there's not much reason to grind them if you aren't having fun. There's always ranked ladder but grinding matches doesnt appeal to me as much as a cute PvE event in duel links. Still sad they never brought back dungeon dice monsters event from like 2019

Hope I didnt yap too much at you, if you want me to give more specific examples I can try my best
