Thick paper, perfect edges, no misprints
When The Melody of Awakening Dragon is activated, players have to discard one card as a cost, which then allows them to add up to two Dragon-type monsters with 3000 ATK and 2500 DEF from their deck to their hand
For example, Feed the Pack and Wolfcaller's Howl are excellent Wolf token producers, but will be worse in super committed Creature-heavy decks that run noncreature hate cards like Ruric Thar, the Unbowed and Nikya of the Old Ways
Dark Magician decks, Red Eyes Black Dragon decks, and Blue Eyes White Dragon decks can all bring out their respective big normal monsters in a flash making this counter trap a fantastically reliable way of shutting your opponent down
(I chose not to count Meteorite, because this deck really needs both red and green mana before turn five)
Most recently, Commander Legends: Battle for Baldur's Gate brought the ancient metallic DnD dragons into Magic: The Gathering
