Unlike starter decks, booster packs contain twelve random cards from Disney Lorcana: The First Chapter
The most common strategy for fighting discard later in the game is to either play everything all the time, which some decks have the ability to do, or to hold land in your hand to shield you
If it helps, think of Items and Characters as similar (Game changing, multiple use), and Actions and Songs as similar (one-use, instant, discarded immediately after use)
Pair either one with your commander or any evasive creature, and youll be drawing cards for days
If it resolves, you'll follow its instructions and the targeted opponent will mill half of their library
it does nothing against decks leveraging the likes of Past in Flames to give flashback to noncreature spells, or similar strategies
