@Mora already pointed this out, but the judge got the ruling wrong
The adventure part of Bramble Familiar, Fetch Quest, has you milling seven cards to return an enchantment, creature, or land from among those cards directly into play
This card's price is maintaining an upward trajectory, with HP copies selling for about $15, MP cards trading at $18, followed by LP copies at around $19.50, with the biggest jump reserved for NM cards, for which you should expect to pay about $36
But I can see this topending a kind of Rakdos removal pile that tips into control from midrange in Standard
Feel free to copy and paste those lists directly into PTCG Live to give them a whirl for yourself
It only costs one mana, so Dragon's Rage Channeler can start making an impact as soon as the game starts
