Gaims toy line sold well in the first Quarter. once the 2nd Quarter started it started to decline due to Yokai Watch & ToQger starting. apparently the Genesis driver wasn't as popular as it could have been (they probably should have done a Kaito upgrade from the get go and marketed as his belt)

There is also a theory that Gaim's after market prices on toys was only due to low production. for example Mango and Kiwi only had one run and stores had signs up saying they will not be able to stock them again.
Also Gaim, Baron, Ryugen and Zangetsu AC's went down in price when they finally had a second run in early 2014.

Wizard was similar. it started good toy sale wise (mostly due to Go-busters toy sales being so terrible, this also helped Fourze have as high sales as it had) but soon as Kyoryuger started Wizards toys plummeted and Kyoryuger dominated.

I would say Sentai is Rider's greatest enemy and Rider is Sentai's but with the advent of Yokai watch (Which is doing double what rider does...which is already doing double sentai almost heh) they have a common enemy toy sale wise ;P
