Aggregate

Aggregate is an unusually awkward card. Although it can provide 3-4 energy quite consistently, it solely depends on when it is drawn. If it is in the bottom 12 cards of the deck, it provides no benefit. As such your deck should be around 30 cards before you consider taking this. It synergises very well with bottled lightning as it can provide a lot of energy on turn one. Despite this, it is still sometimes difficult to use all of the energy that this card provides. For this reason, I rarely pick this card up. Cards that reshuffle your deck increase the consistency of this card.
