You may exile a black card from your hand rather than pay this spell's mana cost. Target player reveals their hand. You choose a nonland card from it. That player discards that card.

1, T: Exile target creature you control. 7, T: Exile target creature you don't control. When Helvault is put into a graveyard from the battlefield, return all cards exiled with it to the battlefield under their owners' control.

This spell can't be countered. Destroy all artifacts, creatures, and lands. They can't be regenerated.

Add BBB. Threshold — Add BBBBB instead if there are seven or more cards in your graveyard.

This land enters tapped. T: Add U. Transmute 1UU (1UU, Discard this card: Search your library for a card with mana value 0, reveal it, put it into your hand, then shuffle. Transmute only as a sorcery.)

(2/B can be paid with any two mana or with B. This card's mana value is 6.) Search your library for a card with mana value less than or equal to the number of lands you control, reveal it, put it into your hand, then shuffle.

1UU: Target permanent becomes an artifact in addition to its other types. (This effect lasts indefinitely.) 3U: Gain control of target artifact. (This effect lasts indefinitely.)

At the beginning of your upkeep, if you have exactly 1 life, you win the game.
