If OMG wins this summer, then EDG (Spring Champion) will compete with OMG (Summer Champion) and decide a winner to advance to S4. He is the seed. The loser decides two S4 places in the same way, namely, runner-up in spring, runner-up in summer and runner-up. If the above teams overlap, they will be dispersed with the decreasing ranking in the summer regular season.
Without the dark horse, OMG and EDG will enter S4.
