6 Consecutive Kira Cards and How to Pick?

From the first day of Mega until yesterday, I managed to pull at least one Kira card in 6 consecutive free draws. I'm here to report that this streak has now ended. My method involved prioritizing packs with bent corners and those that were already face down. ◇While this might not be a 100% foolproof method since 4 seems to be treated as rare, ever since my streak ended, I've been pulling packs that contain exactly one Kira card. However, I haven't pulled any ☆1-3 or 👑 cards at all. My perceived probability is 'bent corner > face down'. I haven't tried sand draws or paid draws, so I can't say for sure, but I suspect this method might work for single draws as well. Since I've succeeded 9 out of 10 times, it's quite a rare occurrence. Settings might vary per individual, or this could suddenly stop working, but I encourage everyone to give it a try!!
