The part that intrigues me the most is Venturing into the Dungeon, but even that seems a little clunky, though it is obviously a late game mana sink
Still, for a long time it was a difficult card to find
They should be a nice little treat alongside the drop, not a card that totally eclipses the others included
Annihilator 4 (Whenever this creature attacks, defending player sacrifices four permanents of their choice.) When Kozilek is put into a graveyard from anywhere, its owner shuffles their graveyard into their library
I could see Hornet Queen hitting $4-$5 easily, which is where the card will end up eventually anyway thanks to casual demand
Obviously you can also just be a total luck sack and tutor up your Reanimate effect and discard the fatty you want to recur from your hand on turn one for the easy mode win
