If you love Beedrill, then love will pull you through.
Also, you maybe able to pull off Agility -> *Focus Strip activates* -> Endeavor, but with a base speed of 75... it'll be hard.
But hey, you still got love, eh?
[EDIT]: Actually even with a base speed stat of 75, if a level 100 Beedrill Jolly IV31 EV252 used Agility, it's speed will end up being 546, so technically you'll be able to outrun a Speed Form Deoxys...
But with the increased number of Quick Attack-type moves in DP, I doubt the classic speed up+Endeavor combo will work.
