cards like armageddon mtg Magic The Gathering Card Destroy all lands. Armageddon : r/mtg

Mine arent the only right answers, and Id probably change my mind if I think on it too long

If you are using it defensively to protect your own spells on your turn, I would cast it in your second main phase, especially if you do not care about attacking

It can't be countered, gives you an extra turn, and shuffles back into your deck if it's somehow put into your graveyard

Maybe something like Mox Opal has them on raw power, but these cards offer broad-spectrum quality

It normally costs twelve mana to activate it, but the cost is reduced by one generic mana for each creature with power four or more your opponents control

This degenerate Gobbo borrows all of your foes mana-producing artifacts when they get tapped, allowing you to absolutely pop off with beaucoup mana taken from your foes mana rocks, likely leading you to a massive turn that might potentially end the game on the spot
