pokemon gotta catch'em all 23k gold plated trading card Charizard #6 in Red Ball 23 Karat Gold-Plated Charizard Trading

Whenever one or more land cards are put into your graveyard from your library, put them onto the battlefield tapped

As a four-mana aura, its good that you can technically use it in a fair way, slapping it onto something as a response opponents removing a different creature (or wiping the board)

In spite of that, I think there's a lot of great ways to make such a deck work and it really shows in a list like this

6: You get an emblem with "Swamps you control have ': Add .'" 3: Target creature gets +X/+X or -X/-X until end of turn, where X is the number of Swamps you control

During your opponents turns, they will be forced to sacrifice a creature
