The Draw phase - this is where your opponent will activate Maxx C to play around Kashtira Fenrir or Triple tactics talent The Standby phase - this is where your opponent will activate Maxx C because they forgot to toggle on and still don't want to play into talents The Main phase 1 - this is where your opponent will activate Maxx C in response to your very first action if they reeaaaaally want that draw The Battle Phase - this is where you either try to immediately end the game because your opponent activated Maxx C earlier on the turn, or want to activate Evenly Matched The Main phase 2 - this is where your opponent will activate Maxx C after you managed to evenly match him The end phase - this is the phase you go when your opponent managed to resolve Maxx C. I hope this was helpful in explaining the different phases in Master duel.
