Requested WoW macro

I’ve been working on this macro for a while and don’t know why it doesn’t work.

#showtooltip Shadow Dance
/use 13
/use Potion of the Tol’vir
/cast Shadow Dance

So I want it to first use my trinket and the potion and then cast SD but it cast first the Shadow Dance and the trinket and potion when I click it again. So it goes shadow dance, trinket and potion with 3 clicks, i just want to click it maximum twice and to use the trinket and potion before the shadow dance not after. Please help me.

When I use Shadow Dance only with the trinket it works together perfectly with only one click but when i add a potion it gets messy.
