Any suggestions for this Zapdos Stall?

Zapdos ( ) @ LeftovesrsBashful NatureTrait: PressureEVs: ??? dunno i traded but there maxed out I’d say 252 atk 252 spe 4 hp•Roost•Thunderbolt•Toxic•Substitute

Okay so the plan is, Substitute right away. Then opponent uses his attack. Use Toxic if they’re not flying. (If they are flying you shouldn’t bother using substitute from the beggining and used T-bolt instead) If your sub broke, use substitute again and use roost after they attack. If it didn’t break, use T-bolt and this will be used until substitute is broken. Now, if you think you can take a hit, use T-bolt. If not, just keep using the substitute roost combo over and over till poison kills them. If you are facing a ground type, not much you can do but get them with poison. If they are steel or poison, you should have switched pokemon before you did anything unless you are facing a skarmory or something you would use T-bolt and OHKO. Sorry this is so long but there is nothing i can do about it. prove your answer and happy mothers day to the usa.

this seems like a good strategy. the only thing i would do is before you send out zapdos have another pokemon set up toxic spikes, therefore eliminating the need for toxic, which would allow another move, also those would be bad ev’s for a zapdos, considering it is a sp.attacker, also I would think that a staller of any kind would want some ev’s in both of its defenses.
