Pray for RNGesus! But seriously, this game is just jam-packed with RNG, especially when the player can't be controlled and you can't choose the orders in which you want to place the block at!
This just leaves you with only few things you can do: Decide what to place given by the object, where to place it, and of course, pray that you won't get hit by a bad object. This game balances it in some way by giving you both the good things and the bad things just like in Super Smash Bros. Ultimate - Hero's down special. I know it can be broken and sometimes I wish it was biased so that the majority of things were good.
