Phyrexian Balrog

Judge 3 (Whenever this creature attacks,
target opponent reveals the top 3 cards of their library.
You choose 1 of them. Then, they lose life equal to the converted mana cost of the chosen card.)
When Phyrexian Balrog enters the battlefield,
if at least 4 life was paid to cast it, destroy
4 target permanents. For each permanent
destroyed this way, its controller discards
1 card, then draws 1 card.
