Hi all

I was wondering if a lvl 12 summon/sac necro is considered bm with vldl duels ? I here clay golem and iron madden is considered bm.
Also I see on the "Low Level Dueling Strategies, Setups, And Guides" sticky there is a few vlld 12 and 15. Are these considered bm ? If any of the items over lvl 9 req.. is that considered bm ?
