war spark booster box of the Pack unite against the elder dragon MTG War of the Spark

(Bevy of Beebles) A new Un planeswalker that unfortunately cant be your commander (but look, were already playing with silver-bordered cards, so why not?)

Endless Ranks of HYDRA is a sorcery that makes a 2/1 menacing Villain token for each opponent, and it returns to your hand whenever your commander enters or attacks so you can keep recasting it

For relatively recent Trainer cards, look to such examples as Great Ball and Hyper Potion

It was a nice touch to add some storytelling to the set, though it hasnt been used since, and the Signature Spellbook series has long been discontinued

That said, there is a possibility that it will be fully transformed depending on the addition of the card pool in the future, so I think it's worth keeping this card in the corner of your head
