I'm playing the Seleuc's at the moment and finding it all too easy. I'm fighting both the Brutii and the Scipii at the moment and I use the pincushion method. That is silvershield phalanx, when I engage the romans I send Kataphraktoi at their back...and the momentum carries tha poor units onto my pointy sticks....never seen units die so quickly.

Another method is the steamroller.....just charge your kataphraktois down hill, they will...eh...steamroller everything in their path. The romans once stationed their army sideways down a hill and I managed to place my 2 kataphraktoi units at their flank while I brought my Silver pikes to their front and then I sent the Kat's steamrollering through the flank of the roman army and they just kept going and going and going until they burst through the other flank of the roman army By that time of course the romans were running away like the girly men they are.

I think using elephants is just cheating....I manage to crush entire armies with couple of units of armored elephants. Managed to crush decent sized armies without losing a single man and that is just cheating in my opinion. So now I have stopped using elephants.
