it's possible to have pills with MDMA and LSD, but it has never been heard of, where as 2C-x being passed off as ecstasy has happened quite a few times. Not to try to tell you what you have or that your dealer is lying, we're just telling you the most likely scenario. I don't think there is a single documented case of pills with MDMA and LSD. Al though it is possible, they are most likely 2C-I or another 2C drug, and also possibly MDA.
edit: I just had DOx sold to me on blotter as acid for the first time in 8 years and some 25 different types of acid I've come across. Drugs being sold as something else happens!
