Kenneth, the new mind

Partner with zulog, cut from the hive (you may have both zulog and this card as your commanders)
Whenever you cast an instant, sorcery or colorless spell, create a 1/1 eldrazi illusion creature token with "Sacrifice this creature: add {c} to your mana pool"
Instant, sorcery and colorless spells cost {1} less to cast for each eldrazi you control
