Psychic Purge

Except for creatures named Akron Legionnaire and artifact creatures, creatures you control can't attack.

Choose one — • Target player gains X life. • Prevent the next X damage that would be dealt to any target this turn.

This creature can't be blocked by creatures with power 3 or greater.

Creatures you control get +1/+1 as long as you control no nonartifact, nonwhite creatures.

Destroy all black creatures.

If this creature would be destroyed, regenerate it. 1: This creature can't be regenerated this turn. Only your opponents may activate this ability.

T: This creature deals 1 damage to target attacking or blocking creature.

This enchantment enters with two intervention counters on it. At the beginning of your upkeep, remove an intervention counter from this enchantment. When you remove the last intervention counter from this enchantment, the game is a draw.
