Latias #1 is shadowed and could be purified for the hundo. #2 is still shadowed, 91%, but the attack is 14, not 15, and further, I have Latias #3, D-max, and 93%, so the hundo is absolutely just for the dex.
We're all familiar with the question by now, but I feel like, for once, I'm presenting an actual dilemma to the sub that different, knowledgeable trainers could answer different ways.
Do. I. Purify?
