I am not sure how you the monsters are placed on the gates.
This is the way I have been playing it until now: Determine the number of monsters that will be drawn from the cup. If they are more that what the monster limit can hold choose the gates that they will be placed on (taking into account the primary gate rule). Draw all the monsters at once. Choose which of them will be placed on the gates and put the rest on the Outskirts.
But after reading some faqs on other questions it came to me that I may be playing the monster surge wrong and I wanted a clarification on it. This is what I think may be the correct way: Determine the number of monsters. Choose gate, draw a monster, place it on the gate, continue this proccess until the limit is reached (taking into account the primaty gate rule). Draw the rest of the monsters and put the at the Outskirts.
So which one is the correct way of doing it? Or they are both wrong and the correct way is something I haven't though of?
