Ah, sloth. My favorite sin, and one that all of us card reviewers must have been enjoying lately, since there haven't been any reviews! Of course, Sloth is also the evil genius of Neopets.com. Sloth's Master Plan, as well as all of Sloth's plans, is very powerful, but has some large problems and drawbacks.

The ability to discard all Villains from play is excellent! This will help get rid of Villains that can't be removed in normal Villain contests. If someone is annoying you with Shadow Usuls, you can get rid of them instead of returning them to your opponent's hand. If someone has teamed up Dr. Sloth with a Symol Warrens, this will clear out that arena as very few other things can. The biggest benefit from this card is against Villain decks. You could wait until your opponent has four Villains out and then wipe them all out at once!

Although this card sounds great so far, there are a few problems with it.
First, you have to tap and discard a card to use it. Obviously, keeping a nice handful of cards is important in any tcg and this one in particular, making this a hefty little cost for playing the card. Also, most players play Villains. This card doesn't just affect your opponent's Villains, but yours as well. You'd need to play this at just the right time in order to avoid destroying your Villain and leaving your own weak arena open.

If you're playing Earth or a lot of people in your area play Villain heavy decks, you'll probably reserve a couple spots for Sloth's Master Plan.
Otherwise, there are other better options for other faerie types.
