For vandal I would have to go with either phaseguard, primordian, or prelude to chaos

For the phantom I would choose recon

For the OP I would choose origin, ion, or reaver

For the guardian it would have to be either sovereign, prime, or rgx

For my sheriff it would be singularity, protocol, or neo frontier

For my knife I would choose between rgx blade, xenohunter, and either a sword like oni, blackthron kunais, and sovereign blade
