Hello guys, I am doing the mega-alakazam quest and I'm having trouble with part of it.

 

I accidentally picked the long compassionate part of the quest, which is fine, and everything is working. But I am on my last alakazam, the one in Sunnyshore city, and it is asking for a Pokemon with high SPATK. I show my fully ev trained, lvl 100, 31/23 gengar, and it says that it does not have a high enough spatk. I then showed it my Heatran with over 360 spatk, and it said that it needed a higher spatk, i showed them my volcanion with over 370 spatk and it still doesn't work. I showed them an alakazam because I thought it was the base stat maybe and it still doesn't work.

 

This whole part of the quest is so vague, does it have to be OT? Is it based on actual stat? is it based on base stat? is it based on IVS? Does it have to be EV-trained? does it have to be level 100? I don't know how I am supposed to figure this out if it doesn't tell me what is wrong with the Pokemon that I am trying to submit. Please help me 

you can lock this, i just tried randomly until it worked
