Although Craniamon is a blocker, I will attack with him under appropriate conditions therefore it is important for him to inherit <SecurityAttack+1> to maximize the damage (since I may not attack very quickly or often). Below are some of the conditions which I consider appropriate for Craniamon to attack:
1. If he inherits <Reboot> from Toyagumon so he can unsuspend at the beginning of my opponent's turn.
2. When I have [ST5-14] Tai Kamiya is in play, with another blocker Digimons so I can block with the other blocker and unsuspend Craniamon through Tai Kamiya.
When Craniamon attacks, he should be at least 13000 DP big (larger if I have more Sistermon Noirs in play) so he will be effective against both suspended Digimons or security checks.
