While it requires a large knowledge of Magic cards and their casting cost (or some fast Googling skills), every card in your hand is effectively every other card of that casting cost in the game
If the top card on your deck is a land, you get to play it, which is great
Fueled by Nemesis legendary Rebel Lin Sivvi, this card in Rebel decks could act as a pseudo board removal, a protection spell in a pinch, or a targeted removal spell all in one truly impressive utility which is just what Rebel decks needed to dominate the metagame
If at least one opponent has more life, creatures, or cards in hand than you, you'll get the appropriate bonus
Thankfully, we have some solid utility lands that can help keep us alive, with Blast Zone working as removal, Mobilized District offering a reasonable blocker, and Field of the Dead potentially making a ton of Zombies if we happen to live long enough to get it going
