Things can quickly spiral out of control over a few turns
Deharme Mill cards in MTG are spells or abilities that remove cards from your opponents deck with the goal of eventually forcing them to lose the game by drawing from an empty library
While resolving Wicked Guardian's triggered ability, you can't have it deal 2 damage multiple times or to multiple creatures to draw more cards
in my second booster, and since I already had cards like Doc Ock, Sinister Scientist, Common Crook, Inner Demons Gangsters, and Mob Lookout, a Black/Blue deck dedicated to villains and drawing/discarding was a given
Or, the colored border around the picture of the pokmon may be printed slightly off center
That means cards like Toxrill, the Corrosive are out since they have blue mana in the activation cost
