With the Necromancer's and Inalla's triggered abilities on the stack, sacrifice the Necromancer to Ashnod's Altar
First, ramp up your mana, boost your power, and reduce the cost of your spells
Like white, blue also polices the battlefield but instead of restoring balance and order, blue selfishly sows disorder to benefit itself
Thus, the play pattern of this uncommon is to cast it, wait until your next turn, and then cast Venomous Words and grant a Creature +2/+0 and Deathtouch until end of turn
Another weirdly-expensive sorcery that feels like you need to be cheating the cost somehow to justify it especially since the biggest appeal would be pinching other peoples artifacts rather than using the token to pressure life totals
