Obelisk of Undoing

2, Pay 2 life: Draw a card.

When this creature dies, destroy all creatures blocking or blocked by it. They can't be regenerated.

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

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

Until end of turn, if damage would be dealt to any creature, you may have that damage dealt to you instead.

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

Destroy target artifact. You gain life equal to its mana value.

Prevent all damage that would be dealt to target creature this turn.
