This booster pack provides some support for this archetype, with a lot of reprints: Card list for the archetype Along the cards added, we can note the new Harpie Perfumer that tutors Spell and Traps from its archetype when its Normal or Special Summoned
Additionally, if no images have been released, we may provide images of previous items in the same series or conceptual illustrations for descriptive purposes (which will be labeled accordingly)
Moreover, Secret Packs become available ONLY after you obtain a corresponding SR or UR card of the said archetype
No - newly played characters have a form of summoning sickness, due to their ink still drying, so they cant quest or challenge until your next turn (unless allowed by an expressly listed ability)
Embercleave only technically costs that much because of its ability: it costs one less for each attacking creature you control
Drawing 15 cards is pretty sweet
