The Vault-Tec Corperation

At the beginning of your upkeep, you may pay 1 life to create a 0/0 {c} Vault Dweller artifact creature token. This creature gets +1/+1 for each other artifact you control.

{1}{u}{b}, Sacrifice an artifact: Draw a card, then discard a card. Vault-Tec deals 2 damage to any target.
{5}{u}{b}: Exile target creature. If it was a creature card, create a 3/3 {c} Vault Dweller artifact creature token. This creature gets +1/+1 for each other artifact you control.
