Mirror Match (http://tvtropes.org/pmwiki/pmwiki.php/Main/MirrorMatch): Aside from the usual, playing against a Darkness player can sometimes resemble one, when their deck can take your weapons, shields, creatures, and the pillars to power them. Or just appropriate the defenses you included against the usual mirror match...Aether can be far worse. Theoretically, an Aether player can set up to play up to 6 copies of every card you draw, on the turn before you even draw it. That includes your quanta generators, so they can use those cards. Realistically, they can often manage at least 2 of your cards to your 1. While humming "Anything You Can Do, I Can Do Better".[/list][/list]
The effect of the "Mutation" card: Mutate the target creature into an abomination, unless it dies... or turns into something weird. (http://tvtropes.org/pmwiki/pmwiki.php/Main/ExactWords)
