There has been a healthy dose of similar cards in Magic: The Gathering in the past, but the difference is that Unmoored Ego can target lands, including basic ones. This opens up some amazing opportunities for completely ruining your opponent's entire gameplan.
Grixis lists ought to have at least two copies of Unmoored Ego in their main decks. Tron and Valakut decks will find it hard to win a game without their precious lands. In such cases Unmoored Ego without exaggeration will serve as your number one win condition.
A similar goal can be achieved in Sultai variant with a slightly more aggressive approach using Tarmogoyf, Grim Flayer and Scavenging Ooze.
