"Poncho", Explosives Expert

If a Soldier you control would deal damage to an opponent or a permanent an opponent controls, it deals that much damage plus 2 instead.

At the beginning of your upkeep, create acolorless artifact Equipment token named Grenade with Equip {1} and "Equipped creature has '{2}, {t}, Sacrifice Grenade: Choose target creature and roll a six-sided die. This creature deals damage to the target equal to the number rolled.'".
