Give the first Pokemon the ability and one move of choice from the second and a stat increase equal to some small fraction of some of the second's stats. Better type synergy results in a larger stat boost, I.E. Grass to Fire is better than Fire to Grass. Certain combinations unlock entirely new Formes for those Pokemon.
