Forum:Hand verification for activating effects


 * Let's suppose player A controls "C-Crush Wyvern" equipped with "B-Buster Drake".
 * Let's suppose "C-Crush Wyvern" is sent to the Graveyard for any reason, it doesn't matter. ("B-Buster Drake" is also sent to the Graveyard.)
 * Player A decides to activate both of them, "C-Crush Wyvern" as Chain Link 1 and "B-Buster Drake" as Chain Link 2.
 * "B-Buster Drake" resolves first and adds "Oilman" from the Deck to the hand. Then "C-Crush Wyvern" resolves and player A Special Summons "Oilman".
 * In cases like this one, how can I be sure player A had an Union monster in the hand at the time in order to activate the effect of "C-Crush Wyvern"? I've read some of the YGOrg's rulings pages (especially https://ygorganization.com/learnrulingspart12/) including a quick look to https://ygorganization.com/perfectrulebook/ to find an answer, but I either look very bad, or there isn't one (at least as explicitly as I would like). Am I allowed to ask player A to reveal their hand? Becasita Pendulum (talk • contribs) 20:50, July 1, 2016 (UTC)
