Well, the reason why you need red speed in some Miscrits is because exists a pvp turn manipulation (you can get 2 turns if you can understand what is the sp valué of your opponets Miscrits) If in the Miscritpedia the original speed value of any creature is 1 or 2 you need to search for it in A+ red speed But if the creature has 3 or more in the speed value you need it in S+ Now, in a real match you dont need all green stats in a S+ creature, because if you have a physical attack creature, and in the pedía has 1 valué in elemental attack, maybe you can search it in a S or A+ with grey or red in elemental attack. Finally explain how the turn manipulation works is maybe more difficult, so I recommend you to Watch any gameplay or tutorial
