First up, take a look at our how to play Disney Lorcana: Trading Card Game guide
Its released at the same time as Shimmering Skies but doesnt contain cards from this set, only from sets 1-4
Hero and Saga are subtypes, not card types
Actions: 4x Develop Your Brain, 3x Grab Your Sword, 4x Let It Go, 3x One Jump Ahead, 4x Smash
Considering that there are many decent low cost amber cards, including several in Into the Inklands, that you can play in anticipation of playing Piglet, Pooh Pirate Captain - this is a card that can get you good head start in gathering lore
Players need to have a deck of at least 60 cards, some cards will be used as Ink to power the spending engine to get new cards into play, and characters can either go on Quests or challenge (fight) other exerted characters in an opponents play area
