Picked up the game back a couple of months ago, I left during the Xyz summons era as a casual player. This has been a trip and a half. I finally understand Pendulum and Link summoning somewhat, although I still get it wrong from time to time. Cards and interactions are complex now, and I have been enlightened to more competitive deckbuilding and card analysis. This stuff is wild, I never realized how deep this game was.
