The creature side of things is Questing Druid, a two-mana green 1/1 that reads: Whenever you cast a spell that's white, blue, black, or red, put a +1/+1 counter on Questing Druid. In the right deck, this card isnt just card draw but a terrifying threat, as it could grow absolutely massive fairly quickly
That keyword appears to be the Vanish keyword: a new ability that enables a character to banish when chosen by an action
Being able to fulfil two rolls at once, both of which highly desirable in control, scaling well into the late game and being instant make it a versatile all rounder not unlike Absorb or Azirious Charm
This dual-threat design allows the deck to pivot its strategy
It creates an interesting decision for them to either save what theyre casting or play an additional spell that turn
Hazoret can't attack or block unless you have max speed
