{t}: Add {1} to your mana pool
Whenever an opponent attacks you or a planeswalker you control that player gets a EXP counter, then that player loses life equal to the
number of EXP counter they have.
"What's EXP? It's an acronym. It stands for
"EXECUTION POINTS". A way of quantifying
the pain you've inflicted on others. When you kill
someone, your EXP increases." —Sans the skeleton
