I try to use my lightning attacks on revenge so they cannot revenge me back.
Over lunch today I managed to find someone with TH in the corner (3 archers took care of that) and enough DE stored to get 800 of it with 2 spells.
I wasn't going to full on revenge the guy anyway, but it was a fun little revenge to get back the DE he took from me with his full attack while my troops were cooking for the next full attack.
