Theres also that random card regrowth that might be breakable with mana accell in the new set.
Serum Powder is not the same as running a 56 card deck. It forces you to mulligan if you have it in your hand because it is a completely dead card, cannot produce mana (because of the investment), and it has the disadvantage of completely screwing you over if you end up removing your one Taiga along with your hand when you use the Serum Powder. GR Belcher needs more mana acceleration, not fluf like Serum Powder.
