yes/no spread (13 card-3 pile)

Wood33

Just a continuation of the last thread. I am wondering about the yes/no 13 card spread. Since I am new to the spread I have a couple questions. 1) How accurate is this yes/no spread if you have the mage and two aces versus having the mage and one ace.
2) Does it matter if the cards are reversed in the readings (does it make the cards any less effective) mage-reversed/ace-upright/ace upright or mage-upright/ace-reversed/ace upright?
3)Will yes/ no spread be more accurate for matters in speculation with money having the ace pentacles/career with ace of swords/love with ace of cups?

Any light that can be shed on this would be greatly appreciated:)
