hour of devastation mtg card Eternity — Hour of Promos (PHOU) | Destroy all nonland permanents. MTG Eternal of Harsh Truths

You pay X and tap it to have it become a copy of a nontoken artifact you control with a mana value of X

And that's before you factor in your Doubling Seasons, your Crypolith Rites, and so on and so forth

Amber & Amethyst: Focused on character recursion and protection

Kinnan doesn't care about any restrictions or riders the nonland permanent put on the mana it produced

Those two-for-one trades are even more devastating when you gain a significant battlefield advantage

Death Toll concerns itself with ensuring as many card types are in its graveyard as possible, so odds are Deluge of Doom will wind up a -4/-4 or even a -5/-5 by the time you want to play it
