Unless you have lots of extra energy sources you probably only need 3-4 horses. Fighting 5-6 glimmer golums per day was about the best I could manage in my first monster hunt and still fight enough of the special monster to get enough tokens to craft it. That's assuming the upcoming hunt works the same way as earlier ones. If it's like the last one and the special monster tokens are only for the leaderboard, I probably wouldn't bother with collecting them at all.
Also the daily goal which requires you to fight fangbeasts is often not worth completing. Don't spend too much energy on trying to get fangbeasts to spawn (the forums are always full of posts about how they've all disappeared during hunts) - that energy is better spent on fighting glimmer golems.
