At the beginning of your upkeep, sacrifice Nature’s Wrath unless you pay .
Whenever a player puts an Island or blue permanent onto the battlefield, that player sacrifices an Island or blue permanent of their choice.
Whenever a player puts a Swamp or black permanent onto the battlefield, that player sacrifices a Swamp or black permanent of their choice.
Nature's Wrath cares about who puts the permanent onto the battlefield, not under whose control the permanent enters.

A single permanent may cause both the second and third abilities to trigger. For example, Underground Sea is both an Island and a Swamp, and Skeleton Ship is both blue and black.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
