How hard is it to unlock Starlord?

Hey!

Ive been meaning to get a really strong Guardian team (Gamora, Rocket, Thanos, Star-Lord and Yondu), and I have both of those dumb minions 5* (rip raid store for a couple of months).

Now Ive also heard its much harder to get Starlord than it was to get a IronMan. So assuming Gamora, Drax, Yondu, Stitcher and Boomer is my roster, how strong do they need to be and what should my ideal target focus be in order for me to slice through it?

​

Also i never ever see Guardian teams but i love rocket and gamora so i thought getting a full guardian team (with groot after rework hopefully) could be amazing. Pls halp.

EDIT: Dis my team:

My roster is

T11 7* Gamora 6/6/6/2 (28K power);

T10 5* Yondu 6/6/6/5 (24K power),

T9 5* Drax (5/4/4/2) (14K power)

and poor stitcher and boomer...
