As someone who really didn't get into the latter part of 5Ds or Zexal, I'd say give Arc-V a shot like I did. It starts slow, but there's enough plot movement to keep your interest through the slower parts. I like especially how there's quite a bit of episodes where the Duels are placed in the background in favor of moving the plot forward, more frequently than the other seasons did. The worst part about Arc-V are the Duels, honestly, but it's great to see them use all the Summon Methods.I'd read up actually on Synchro and Xyz Monsters from 5Ds and Zexal respectively, just so you'll understand how they work.
