The mana of the Cube is designed to make two-color manabases really strong, and this theme allows black to play especially well with white and red, which goes a long way towards making sure that black is represented in decks
Energy is a type of bonus resource, almost like mana, but it sticks around forever, or at least until you spend it on some spell or ability
Enhancing the Strategy : Phyrexian Reclamation, Taurean Mauler, Quicksilver Amulet, Blood Speaker, Blinding Angel, Cryptic Gateway, Cauldron Dance, Aegis Angel, Steel Hellkite, Rune-Scarred Demon I chose these cards to enhance Kaalias strategyproviding some additional quality Demons and Angels (including Aegis Angel that can protect Kaalia), ways to make sure youve got a handful of boom-booms, and then alternatives to Kaalia when shes indisposed (Quicksilver Amulet and Cauldron Dance)
This card would eventually be retrained as Mementotlan Ghattic
It's Special Summoning effect makes it all but mandatory to use as a Link Material for the next card
