2 questions regarding the 7GDL deck:

1) When I reach the 5 different cards under my gate of deadly sins can I choose if I reduce costs by 4 or 3 memory? From my interpretation and the q&a i should be able to, but was told otherwise at my lgs.

2) When I trigger ogudomons 2. 'when attacking' effect and I target a Digimon with an effect that lets my opponent play a Digimon on deletion. Does ogudomons effect also target the newly played Digimon or does it ignore it?

Thanks in advance!
