First up, here are some things you can expect:

• a new type of token (at least done as a cohesive theme)
• a card that can activate to copy enchantments
• Adventures on a new permanent type
• an artifact that has two different artifact subtypes normally associated with artifact tokens
• a creature type from Alpha gets a draft archetype
• fairy tale Sagas

• “exile up to one other non-Fox creature”
• “Land creatures you control”
• “Whenever you tap an untapped creature an opponent controls,”
