I agree Accelerated Armagios is surprisingly brutal against these Elders. 6 Armagios, 5 Accs, 3 GP's, 3 Momentums (or 6 Accs, 2 Momentums), a Short Sword and 12 pillars.
Chargers would be better if they didn't die so easily to the large amounts of CC the "new" Elders have. Both decks are, however, cheaper and better than packing Colossal Dragons.
