If you're having MAJOR trouble with an opponent, don't be afraid to make a Tech pattern to defeat them. My starter tech pattern for a Psi was always Psi Blast > Forget *insert troublesome technique here* > Brain Chill > Mana Shield > Torment > Weapon Attack. After that, then you react accordingly to the opponent. You will FAIL if you just try to attack and don't debuff and buff yourself.
Playing a Psi game now and they seriously own with Wall of Atoms > Psi Blast > Mana Shield. If you watch the enemies movements VERY carefully, you can wipe out a lot of guys while no taking a lot of damage.
