A deeper inspection into these playtest cards shows a wild and diverse (and very concerning) trend: While three to four of these cards are showing up in secondary markets at less than ten dollars USD, the value of these cards is extremely jumpy, with some being as high as nearly $350 USD
If a booster is worth around $6$7, thats roughly $20 of value just in packs
This card is really pushed and is almost always worth taking as your pack one, pick one in a draft unless you get an insanely strong rare
I really cant see any reason youd want this to be legal
Tinybones, Trinket Thief is a two-mana 1/2 that, every end step, lets you draw a card and lose one life if an opponent has discarded a card that turn
Most extra-turn spells cost five mana or more, which explains why its such a massive outlier in power
