We recently saw Psychic Possession soaring in price, and before that a very narrow counterspell spiked surprisingly hard
The White one-costs three for a 2/1 lifelink that turns ETBs of smaller powered stuff into cards drawn, but just once per turn
Mycoloth (53k decks, SL foil $24) The other Mycoloth has a lettering/look that some dont resonate with, but the bigger problem is that this card is all building towards playing a huge creature and hoping it survives a turn
It is also the first level 3 assistant added to the explorer
And reading this card made me feeling like I was right there in Dunwich, creeped out by the sordid and silent locals
Beluna and a handful of other cards notably offer support for Adventures as more of a macro theme as well, which opens up the space to Cube with cards like Edgewall Innkeeper and Lucky Clover
