Infernal Shrine

Battleground
When you play Infernal Shrine, search your
library for a basic land card, put it onto the battlefield, then shuffle.
At the beginning of each players upkeep, they
create a 1/1 colorless Guardian creature token.
Whenever a token creature dies, the player who
killed that creature gets a shrine counter.
When a player has forty or more shrine counters, sacrifice Infernal Shrine and they create a 10/10 colorless Punisher creature token.
