AboutPatrick Expertise I can answer any questions about RULINGS only with the Yu-Gi-Oh English TCG. I get my information from the official source, so if you tell me something that contradicts the official rules, I will give you the exact ruling(or similar situation) with explanation. My advice to you is get the rulings on every single card in YOUR DECK before starting to duel!
A good site to look for rulings would be(updated as new boosters are released):
I CANNOT do deck fixes, as I pay attention to the rules more so that everyone plays it right. If you ask me for deck fixes, I will immediately sent it to the Question Pool(No, this is not rejecting your question).
NEWS: Konami reclaimed all operational and business aspects of Yu-Gi-Oh. Upperdeck Entertainment no longer has control in the United States.
UPDATE: Down to 3 questions per day. Hopefully, there will be no problems with my connection. Be clear and use punctuation. Nothing related to deck fixes/checks/ratings or card prices/trades/whereabouts.
NOTE: This should not happen, but I'll post it here anyway: Due to limited connectivity to the internet/personal problems, I am terribly sorry if it takes me more than 24 hours to answer your question. If you send "non-ruling"-related questions, do not expect a reply.
Experience I know the rulings.. and I only get them from the official source. Even then, some people will do anything to win(even if it goes against the rules), such as arguing who's right and wrong.

Question This card's effect is "You can Normal Summon 1 additional time this turn. You can only gain this effect once per turn." so does this mean it's continious or not.
Answer It's not Continuous. No matter how many copies of Double Summon you activate, you can only gain the effect once per turn.
RULING: "You can activate multiple copies of this card in the same turn, but you can only gain 1 extra Summon per turn from this card."
