I finally caught a Shiny Maltres tonight. So random and thankfully you don't need a Master ball. Word of advice. When using your daily incent. Make sure you have well over 100 balls. It took over 10 minutes and lots of throws. I figured out after my adrenaline settled that the bird will start up hi𒉰gh then get lower in 3 phases. You can only hit him when he is lowered. He won't flee so take your time after your heart calms down and you can breathe lol
