Since the new movie is all about it, I figured it's time to reflect back on one of our favorite gimmicks: Combination. What's a good combiner for you? Where does the sacrifice get made? Vehicle mode? Bot mode? Combined mode? For instance, Magnaboss and Tripredacus are two of my favorites. Magnaboss looks impressive, but his toys are all about him, rather than themselves. Conversely, Tripredacus's components are more fun as a whole, but the combined mode isn't as cohesive. So talk about 'em all. Your favorites, your preferences. Just let's try to avoid 15 pages of "Rail Racer is the best."
