If the hybrid mana rules change comes into effect, Ashiok will become a fantastic option for such decks overnight, particularly those like Bruvac the Grandiloquent that pursue a Mill strategy
They also include ten double-sided token cards, a strategy insert, a reference card, and a deck box designed to hold 100 cards with sleeves
This card may technically be colorless but we all know its a green card, and both Conspiracy sets have tons of green creatures that synergize well with each other
It's slightly bothersome that the power and toughness box is on the left side of the card, but it's visible and fits the geometry of the art well enough.
If you use something like Jetron, you can use the used arkanite as a material for an 8-star synchro, so there is no waste
