Just like Path to Exile, it's actually card disadvantage, (you trade your card to exile/destroy one of theirs and they get a land - total cards - You lost 1, they lost 1, and gained one, for a net of 1 card their way)
This Tarkir: Dragonstorm Sultai Arisen Commander Deck includes 1 Black-Green-Blue deck of 100 Magic cards (98 nonfoil cards and 2 Traditional Foil Borderless Legendary cards), a 2-card Collector Booster Sample Pack (contains 1 Traditional Foil or nonfoil alt-border card of rarity Rare or higher and 1 Traditional Foil Uncommon card), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 strategy insert, and 1 reference card
It goes hard with a fetch land and Crucible of Worlds
The first is you make a cool design and either turn it into a character or happen to find a character that's a great fit for it
Magic Online might be ugly and buggy, but it does more or less do its job
