Kolaghan, the Storm's Fury buffs up the dragons, stacking with Heraldic Banner to make everyone a bit more stronger.
Silumgar, the Drifting Death helps keep opponents stronger creatures down. Considering damage spells like Lightning Bolt to finish off what does not die.
Nicol Bolas, because you can't have a Bolas deck without him. Keeps opponents hands empty.
Nicol Bolas, Dragon-God to give us win con, and for flavor.
*Also considering swapping out some Nicol Bolas, Dragon-God for Nicol Bolas, the Ravager
Heraldic Banner is used to generate black mana and give a small power buff. All creatures will benefit if black is chosen.
Pentad Prism for charging up unused mana for later turns.
Mana Leak for buying time.
Grixis Charm can recover a dragon, weaken a creature, or buffs for a all out attack.
Crux of Fate clears the field, assuming they are not also running dragons.
