Actually it's very very easy to have 7 or 8 teams of Wind Riders.
You need two cheats to help you out: pointbreak & greedisgood 1000000.
First, built 12 Beastiary. THen,select them all and hit "W" key (Hotkey for Wind Rider) continuosly. Make sure that your food or upkeep doesn't exceed 45 or else those Wind Riders can't come out as the food already reaches 100 before the second team can be produced.

You can do this with anything, just more or less depending on 2 things:

1. How much space you have left before max
OR/AND
2. How much space they take up (like if you want to create more than 7 teams of grunts, you'd probably get almost 10).

Try it with everything!
