I do not deal in such things at all
Landfall is a well-tread strategy, especially after the influx from Zendikar Rising, which I believe could negatively affect Maja's numbers, since it's swimming upstream to make a place in an already extremely crowded field
Chaos: Whenever you roll Chaos, target player reveals the top card of his or her library
The good things about this deck: I don't disrupt the opponent, letting them combo as much as they want, which lets me get a good look at their deck
however, youll only really want to pick one of these up once youve got a functioning deck already, as it would not provide you with enough cards to build a functioning, playable 60 card deck in itself (unless you happened to be incredibly lucky with the booster packs it contains!)
