To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Serpent of the Pass's second ability)
When the last counter is removed, you can play them without paying its mana cost, and if its a creature, it gains haste
Since youre already playing black, you probably have sacrifice outlets anyway, meaning you can get rid of Kothophed before it gets too dangerous
K'rrik, Son of Yawgmoth joins Necrodominance as something that either makes Death's Shadow pop off or just lets them kill you faster
Facilier, Agent Provocateur Rarity: Rare Cost: 7 Ink Strength: 4 Willpower: 5 Lore: 3 Effects: Shift 5 - This character only costs 5 Ink if played on top of another Dr
Theres definitely a little bit of controlled chaos mixed in here as well with the focus on cascade and similar effects, helping to keep this deck fun and interesting to play
