Playing dragons smart

So at GenCon the guys who run D&D at Wizards have a 20th level game call "Dungeon Delve" where they take 20th lvl characters and put them on one sheet of paper that is easy to figure out. The idea this is a one shot dungeon scenario vs. some dragons. Last week I read about the characters they pre-designed and this week covers the dragons. My favorite part is the R&D note on dragon's and spellcasting. It's hilarious :D
