text: If multiple phases are added to the same point in your turn, the most recently created phase happens first. For example, say Obeka deals combat damage and its ability resolves during your combat damage step, giving you two additional beginning phases each containing an upkeep step after this combat phase. During end of combat, another effect gives you an additional combat phase after this combat phase. The additional combat will happen first, followed by the additional beginning phases containing the two upkeep steps.
