Cannot be Normal Summoned/Set. Must be Special Summoned by "Armed Dragon LV5", and cannot be Special Summoned by other ways. You can send 1 monster from your hand to the Graveyard; destroy all face-up monsters your opponent controls with ATK less than or equal to the sent monster's ATK.
A "R" card is lv 40 reward card for The great Chazz.. How cool is that? And also a drop reward for serious Chazz now I got like 6 copies so minus the one I got through grinding I would still end up having 5 copies anyway heck even AD LV5 which is a "SR" has a lower drop rate imo. Just sayin
