For context, I paid about $4k for a box around 2018-2019 they peaked over $30k and are back around 20k today
My advice: add a clause, "This card is also treated as a Spellcaster-type monster while on the field, in your hand, or in the Graveyard." In summary, I really like the card
Once per turn: You can detach 1 material from this card, then target face-up cards your opponent controls up to the number of "ZW -" Monster Cards equipped to this card
Puoi utilizzare questo effetto di "Uccello di Tuono Tempesta" una sola volta per turno
You can also -1 it to draw the card that they didn't give you later, so you are drawing a card every turn for four mana, no matter what
For only three black mana (perfectly priced to be cast with Dark Ritual!) you could turn any amount of life you were willing to pay into fresh cards off the top of your deck
