Sacred Cards has a route for Destiny Board manip which i'm trying to reproduce with TAS tools even though i suck at this, game's fun though and i really recommend it:

Reshef also has the same RNG manips but it's a much longer game with different strats.
The main difference in strats is that Destiny Board FINAL are very cheap and acessible with passwords on Sacred Cards speedruns, but extremely expensive in Reshef to use and gather. On the other hand, Exodia would be very useful for Reshef as he's a little cheaper and would instantly win against enemies with gigantic HP values. Because Exodia is limited, a strategy to win against some gauntlets would be needed still as i believe it might be impossible to RNG manip those gauntlets for multiple Exodia wins if you only have 1 copy of each part. The egyptian gods could still be manipulated with messenger of peace to be available in most fights still for the gauntlets and maybe Darkflare soldier as well.
