>>18598121Without destiny knot you only have about a one in a thousand chance of getting 5IV, even assuming perfect parents, so it'd be faster to use destiny knot but no everstone, and go for nature randomly.
So get a 5/6IV Pikachu and 5/6IV Ditto
Destiny Knot on Ditto, Light Ball on Pikachu
Will still take about 150 eggs on average though, since there's the 1/6 chance of getting the right five IVs, and 1/25 chance of getting jolly.
