Patron of the Past

Reach and Protection from White
{t}{2}:When you cast a non-creature spell, choose one:

•Place X rust counters on an artifact where X is the mana cost of the non-creature spell.
•Place X rot counters on an enchantment where X is the mana cost of the non-creature spell.

(Player sacrifice an artifact/enchantment at the end of their end step if any rust or rot counters remain. Players may remove these counters by pay mana equal to the number of counters.)
