Panda-Dreadnaught
This deck is very surprising to say the least. A good way to kill is to have enough mana to throw out a pandemonium, phyrexian dreadnaught, and a tinker(for a phyrexian Colossus)in one turn to deal 20 damage at once. Another sneaky way to go about this is to let yourself discard a either colossus\' and use the goblin welder\'s ability to switch a colossus into play for free. Say you have a pandemonium in play and a welder has been play for a turn, tinker something usesless like a 1/1 Shifting wall for a Phy. Dreadnaught, it deals 12 then dies, then switch it back in with another artifact for another 12!! Also, you can pump up a Shifting wall with all the mana you have for big pandemonium damage. Flings also work wonders with a dreadnaught. I would appreciate any suggestions or comments on this deck.
