The Process

No player may control more lands than the
number of turn cycles that have passed since
the beginning of the game. Players that control
more lands than the number of turn cycles
must sacrifice lands down to the number of turn
cycles. Artifacts, creatures, and enchantment
abilities that would add mana into a player's
mana pool cannot be activated and do not trigger.
"Today's society wants to skip the process. I hate
that" -Tom Izzo
