What kind of toys to diamond doves like to play with?

I am afraid that Doves/pigeons are not interested in toys at all.....all you need is a cage big enough that they can flap their wings some, some secure perches so they can mate comfortably and a nice respite where they can carry a few stems of dried grass to make a nest to lay their two eggs and rear their babies.....they are not really people oriented either..If you will keep a pair together in a cage by themselves with good seed, clean water, grit and some dandelion greens they will be very content......
