On first glance frost and treat are bad. Then I realized that they’re actually really good in some ways.
Treat and Frost provides graveyard utility and fixes the negate problems that the twins have (where they just die to one ash)
Plus frost is an aqua so she can help make toadally awesome and treat is a dark so she can help make number 65. Both negates
So I took a control spin with knightmare for this deck and it works like a charm!
