The main reason you see and play Vraska's Contempt over cards like Ruinous Path is for that instant speed
Five mana is a lot but we can copy protective instants and countermagic on their turn to keep Alania around
And Im willing to pay 6k at this point in time
Magical Charm, Sylveon exs first attack, deals 160 damage while reducing the next incoming attack by 100 damage, which is a nice cushion for keeping Sylveon ex safe
Sure, it might stretch the definition of what a Goblin is, but it has to qualify, as both sides of this card produce a Goblin creature, either in token form on the front or as a zero-mana-value enchantment creature on the backside
For example, you might combine Bolas's Citadel and Aetherflux Reservoir, giving you card advantage and life to offset the life loss, or maybe have reanimate loops using Chainer, Dementia Master and Gray Merchant of Asphodel
