lets say i have "Foolish Mass Burial" and "Monster reborn" in Hand
1. i aktivate "Foolish Mass Burial" and send a "Crystawing" to the Grave
2. i cant aktivate Monster reborn to specialsummon the Crystalwing

i dont know if i am wrong but this should work[:confu:]

ill hope you fix it. thx for suport [:thumbu:]
There is nothing to fix since it is working properly
An Extra deck monster need to be properly summoned to be able to be summoned back
Since CWSD wend directly from the Extra deck to the GY, it was never summoned properly, and so it cannot be summoned using monster reborn
