More Magic nerd stuff, because I'm a nerd. If you don't play/understand Magic, you will not understand the following paragraph. But you should totally learn. Because collectible card games are fun .-.
The new set made mono-red goblin mill a totally (read as: not at all) viable deck. Altar of the Brood and Altar of Dementia with a bunch of goblin token cards and Krenko, Mob Boss results in hilariously inefficient, but ridiculously trolly, mill. Basically, Altar of the Brood takes 1 card off every opponent's library when I get a permanent (which is practically everything), Krenko creates X 1/1 goblins (which are permanents) where X is the number of goblins I control, and Altar of Dementia sacrifices a creature (which are what goblins are) to take X cards off target player's library, where X is the creature's power.
Literally, the sheer presence of goblins will drive you insane.
