By Invitation Only

Each player chooses any number of creatures they control with total power 4 or less, then sacrifices all other creatures they control.

Each player chooses a party from among creatures they control, then sacrifices the rest. (To choose a party, choose up to one each of Cleric, Rogue, Warrior, and Wizard.)

Each player chooses from the lands they control a land of each basic land type, then sacrifices the rest.

Choose a number between 0 and 10. Destroy all creatures with power greater than or equal to the chosen number.

Each player chooses a creature or planeswalker they control, then sacrifices the rest. Players can't cast creature or planeswalker spells until the end of your next turn.

For each player, you choose from among the permanents that player controls an artifact, a creature, an enchantment, and a planeswalker. Then each player sacrifices all other nonland permanents they control.
