I'm actually very surprised no one on your staff
thought of this:
Amazon Swordswoman equipped with Ring of Magnetism
and Heart of Clear Water.
Ring of Magnetism decreases the Swordswoman's ATK
to 1000, so it can be equipped with Heart of Clear Water. It also makes it
so your opponent can't attack any other monsters. So, you have a monster
that can't be destroyed in battle, and is the only valid target for your
opponent's monster attacks. This way all you have to worry about is
opponent's card effects; Dark Hole, Raigeki, Dark Dust Spirit, Cyber Jar, or
even Man-Eater Bug.
Add Lava Golem to the equasion, and you've got your
opponent on the ropes. You can slam your Swordswoman into the Golem over
and over again, and the Golem will add in that extra 1000 LP
damage.
