Forum:Gateway of the six+Double edged sword+ X2 grandmasters???

So I was wondering if I have 1 grandmaster on the field, and 1 in the graveyard, if i use Double Edged Sword Tech, can i summon a grandmaster and have it destroyed right away because you can only have one Grandmaster on the field, and add 2 counters to the Gateway of the six. is this right or can i not summon Grandmaster at all????
