Regenesis grind game is absolutely crazy. It's funny to set up a mediocre board that the opponent plays through but stops them from going full combo, then they surrender in the end phase after realizing that every single one of your monsters is just adding itself back to hand to summon again next turn.
I've bricked completely on non-engine and had this trap completely carry me with its Foolish getting you free followup as cost for Book of Mooning the opponent every turn.
Then even if they cut off your resource loop by banishing, the spells and traps just have bonus effects to get them all back anyway.

I wish it had some more engine cards so you didn't have to supplement with additional stuff, but even then getting to use like Nadir or Lava Golems is fun too.
