Lockheed Martin

When Lockheed Martin, or any other creature, enters the battlefield. Stack a die on top of the card (all dice must be stacked vertically)

Lockheed Martin gets +2/+2 for each die in its stack.

Lockheed Martin attacks each combat if able.

When the dice stack falls, sacrifice Lockheed Martin.
