1- T50 =/= AI5
2- Change mark to earth, add some Lava golems and free criatures (photons/sparks, your call) and throw in 6 Immolations as you reduce the number of dragons to at least half of what you have (better with 1-2) and keep only 5 pillars. Consider throwing that RoF out it's too situational (ie, only good against RoL/Hope). Take a hammer with you for extra fun.
EDIT: as you don't have the electrum, kill some AI3s until you can afford those changes. You can sell up to 4 of those dragons. They are pretty much useless.
