Grand Aether Council

At the beginning of you upkeep you may put a colourless 1/2 spirit council creature token into play under your control.
Spirit council tokens you control gain, {1}{w/b}: sacrifice this creature, add {1} to your mana pool.
Thousands of thralls flock to watch Taeboch's Judgement pass, as the eons pass in his deliberations. Their zealous devotion sustains him, as they wither with the passing of time.
