By putting 5 [Hybrid] cards under Kanbara, and opting to digivolve into a LV4 hybrid (such as Agunimon) instead, leaves the door open for a larger variety of further digivolutions: one such route would be to digivolve into [BT4-113] Ancientgreymon instead (through any other LV5s, preferably a 1-cost hybrid), which would make for an insane 8 security checks in one hit, potentially bundled with other effects such as option jamming and piercing.
Under a similar configuration, one can also digivolve into a [ST1-11] Wargreymon for a simple 5 security checks (though this is far less effective compared to Ancientgreymon).
