Forum:3 way dule deck building?

Duel*

In any case, me and two friends usually duel by all three of us going at once. Does anyone have any tips for building a deck that could survive being double teamed at any moment?

Opponent 1 uses a 6 Sam/5D Starter Xsaber deck, Opponent B uses a Dragon deck that just keeps getting dragons out, or a burntastic fire deck.

Any and all thoughts would be welcome, I would just like to note that my card selection in quite random. 5000~ cards with only a few u/s/rares. (Though some normal copies of rare cards.)
