Largepox
Sorcery
Each player discards a card, then loses 1 life, then sacrifices an artifact, a creature, an enchantment, a land, a planeswalker, and a tribal permanent, then exiles a card from their graveyard, then puts the top card of their library into their graveyard, then removes a counter from a permanent they control, then gets a poison counter.

While resolving Largepox, first the player whose turn it is chooses a card in hand without revealing it, then each other player in turn order does the same. Then all the chosen cards are discarded at the same time.

After each player has lost life, the player whose turn it is chooses a permanent of each listed type. One permanent can’t be chosen twice this way, and that player skips any types of which they don’t control a permanent. Next, each other player in turn order does the same, knowing choices made before them. Then all the chosen permanents are sacrificed at the same time.
