Attacking Farmer at lower level

I have found an interesting strategy on how to attack farmer while farming at the same time.

Most decent farmers like to be at around 150 trophies range (and around 1250, that's a different strategy) so i get down to below 300 by 10-20 trophies and wait to be attacked by a single guy army (farmers lowering their trophy count) and then I just revenge to see how much gold they have and "end battle" to build an appropriate army.

Also, don't get rid of the graves. they don't give you much elixer, but they do make it seem at a quick glance that the player stopped playing the game. Thus, making it seem to a decent player that you won't revenge.
