Artifact Creature â Knight
Whenever you cast a silver-bordered spell, put a +1/+1 counter on Border Guardian.
Whenever you cast a black-bordered spell, Border Guardian can't be blocked this turn.
Whenever you cast a white-bordered spell, Border Guardian gains double strike until end of turn.
Playing a land wonâ€™t cause any of Border Guardianâ€™s abilities to trigger. But for the record, Unstable basic lands donâ€™t have a border.
