yugioh card destroy spell trap Iron Thunder - Phantom Nightmare and detroy that card. Destruction Jammer - Yugipedia

This 4-mana 3/4 legendary soldier locks down your opponents during your turn, which negates any attempts at combat tricks

Tamiyo, the Moon Sage originally came to Innistrad from her home plane Kamigawa, so it makes sense that she hearkens back to some of the cards from the Kamigawa block we mentioned earlier by giving her controller an emblem with You have no maximum hand size (the second line of that emblem is perhaps the most devastating to your opponents, but you can read that line on your own)

discard a number of cards in your hand equal to the Level of that monster, and if you do, draw that many cards from your Deck, then, return the targeted monster to the owners hand

Since the Dragon-type was not introduced to the TCG until the Black & White era, all of them used either the Colorless type or their secondary type until then
