Going from level 3, to level 5, 7, and 10, the armed dragon monsters all have good attack and strong effects. While seemingly difficult to summon, there are some support cards that can be used to get these monsters out quickly, like Level Up!, or Level Modulation.
It's quite possible he actually does. He has fewer SR/UR cards than most of the DM characters, and it's quite possible each card is its own "slot" on the potential drops, meaning more potential cards increases the odds. Just a guess, but it's plausible.
I got armed dragon lvl 7 and 10 from battling chazz at lvl 10 and 20.. both battles was a loss and to my surprise I got those 2 cards... I also got lvl 5 armed dragon from chazz at lvl 20 and 30. Won both of those.. of course it wasn't back to back but that's how I got them.
