Dross Harvester was never really a good card, and this deck not exactly being one that picks off creatures en masse often doesn't help either
I want to reemphasize that these cards are usually being sent from individuals , not full storefronts, so theres less security when it comes to judging card conditions, returns, etc
Players create a token that's a copy of the creature under control, before sacrificing it at the beginning of the next step
Raw refers to ungraded cards, and PSA 10 refers to highly evaluated, graded cards
It isnt down-to-the-card accurate (more on this in a sec) but it is a really good ballpark
Unlike other games, gift cards cant be given to your opponent in Magic , as the equip keyword dictates you can only target creatures you control
