Hero is an attacking card and wants to be in a deck that is setup to attack effectively
the Pok Pad from Ascended Heroes has already shown there is more interest here than many would have assumed
Arceus & Dialga & Palkia GX Whats better than two Legendary Pokmon on the same card
The Queen also appears in regular and extended-art versions in The Brothers' War
You can have red, black, and white cards in your Extus, Oriq Overlord deck, but you cant include it in your Teysa Karlov deck
Whenever a creature with power 1 or less is put into your graveyard from the battlefield, you may return that card to the battlefield at the beginning of the next end step if Shirei, Shizos Caretaker is still on the battlefield. Basically, youre going to fill the deck with cards like Viscera Seer, Zulaport Cutthroat, Yaroks Fenlurker, and Big Game Hunter, and just recur them for all of time until you win the game through sheer force of will and the little people fighting back
