If you want T1 or T2(Def,MD,Cap) keys you only have to farm up to 10 waves no more if more you will only get T3. Not to mention that Earth and Venus, first 5 wave is T1, 5-10 wave is T2, 10+ wave is T3 keys. While Jupiter and Mar is T2  goes up to 10 wave and after that its all T3's. my suggestion if you only need T1-T2 stop at 10 waves. Higher planets than those 4 all drop T3's it doesn't matter which wave you are at.

other than T2 Raid/Exterminate is a common reward so its everywhere.
