Eye of Nidhogg overwrites all previous effects that set the creature's base power and toughness to specific values
Amethyst cards are usually magic-focussed, Amber relates to healing and protection, Steel and Ruby cards tend to have higher challenge power, Sapphire is more strategy-focussed, and Emerald is a bit of everything
These four puzzles, Sapphire, Emerald, Amber, and Ruby, will be released at all retailers in September and the amethyst and steel puzzles will be exclusively sold at Disney stores in the United States, but in Europe all six puzzles will be sold at all retailers
Lastly, Cursed Merfolk is an excellent one-cost character to include in a deck like this, letting you quest for two lore as early as turn two, and handily speeding up the game for you
