Im receptive towards the idea that this decks success has as much, if not more, to do with Goldspan Dragon than Hullbreaker Horror
Sephiroth, the Savior Four colors and 7 mana, but basically you win the game. Ideally youll get Atraxa, Grand Unifier earlier so you can build around it, as its among the best payoffs for UGx Towns
Plus, the new Vanish keyword makes its grand debut here
These are the Madam Mim and Merlin cards with effects when entering or leaving play
It's also the cheapest item in the set at $19.99 , so a perfect place to start
Broadly that side of things was covered in the white weenie archetype breakdown and so despite them being viable additions to these decks I am going to mostly avoid talking about them
