@Eclecto: Actually, multicolored decks let you use some nice strategies. I have a blue/purple deck that combos purple's "all creature's base power is 1" with blue's cheap, aura-upgraded robots to basically make my opponents all have 1 power and mine have 2 regardless of cost. Really makes games difficult for the opponent, and makes those robots useful!
Remember... the computer is a computer. Ideally, you, being a human, are smarter than the computer, and know how to take advantage of the fact that the computer has twice as many guys as you.
Fun, but it has more bugs in it than Men in Black. :)
You have been cursed with my bad joke of the month. :P
(Normally, that would be followed by a "copy and paste this five times" message... surprised that it isn't?)
I've played this like 4 years ago on a different website. I don't know if I'm allowed to say it (some forums have obvious rules against potential advertising), but something smells fishy here.
