In the Trenches{1}{W}{W}
Enchantment
Creatures you control get +1/+1.
{5}{W}: Exile target nonland permanent you don't control until In the Trenches leaves the battlefield. Activate only as a sorcery and only once.
The battlefield became so pockmarked with craters and trenches that casualties were regularly attributed to "fell in a hole."
