you arnt stupid at all. back in the day (when 6th was JUST in print) i had a Wall Deck, and TRUST ME, there is nothing more funny than watching your opponent die by your wall.
the way i played it was QUITE expensive, with 12 duel lands and 4 mox diamonds, but you can run it cheaper.
the creatures
4 Sunweb
4 Blistering barrier
4 flowstone wall
4 mobile fort
4 necropolis
4 shifting wall
4 snow fortress
the others
4 Rolling Stones
4 Conspiracy (to make them all a different type of creature)
4 Mox Diamond
4 Harrow (relies on getting the mox)
the lands
4 badlands
4 plataeu
4 scrubland
4 plains
4 mountains
it is kinda slow, but for Casual, there is almost NO deck more fun.
