They say that pack mentality gives 30% boost to strength and magic if all three monsters are same class. Role resonance should give 20% when using all same role like triple disaster or cerberus. I don't even have the role resonance infused but still have no trouble whatsoever beating enything with that red chocobo. Of course one could play with chichu/nanochu/microchu deck but then you would be stuck with two SYN monsters.
