This went 8-2 for me through Plat 1, with a little luck and opponents seeming unprepared.
All the units are chosen to carry weapons well, but there are a couple you really want your Gemblazers on if you can choose. Crownwatch Paladin
and Iron Priestess
both mitigate the 2-for-1 penalty normally associated with playing weapons. D'Angolo Houndmaster
sometimes activates, but he can also be bait to attract your opponent's removal spells before you commit with a weapon on something else. This deck is not designed to empty the hand lightning-fast, so if you fixate on activating Houndmaster, you'll be disappointed.
