if they killed it is their fault tbh
yes, those are the only obtainable
you havnt ever misclicked? not everytime they kill its their fault, but my option might be the best only let those who killed/disconnect be able to recatch , i think it was doggy dat lost his mew due to crash.i understand that they dont give back lost pokes for crash but legends is a diff issue is it not?
that's why im suggesting this if you killed it or lost it by rollback you can wait an amount of time to have another shot.
Mew and celebi are very powerfull in pvp and I'm agree with not being tradeable but lets be honest the chance of getting a decent for pvp in one oportunity it's very low
