"Find me cards equivalent to: Roiling Horror"

Equivalent cards to Roiling Horror (Mono-black, Creature — Horror, variable P/T based on life):
1. Serra Avatar (White, but similar variable P/T based on life) – Not black, but for reference.
2. Necropolis Regent (Black, interacts with +1/+1 counters and life swing, but not variable P/T)
3. Aether Snap (Black, interacts with counters, not a creature, but related mechanic)
4. Death's Shadow (Black, gets bigger as your life gets lower; 13/13 - variable power/toughness relevant to life)
5. Bloodgelder / Phyrexian Negator (Black, but not similar P/T)

Closest black equivalents:

  • Death's Shadow: Variable power/toughness linked to life totals.
  • Phyrexian Devourer: Can manipulate its power, though not life-based.
  • Ebonblade Reaper: Life total-based interaction.

None matches exactly, but Death's Shadow is closest:
Text: Death's Shadow gets -X/-X, where X is your life total.
Reason: Power and toughness changes as your life changes, like Roiling Horror.

  • Phyrexian Devourer’s first ability continually checks its power as a state trigger. Once it triggers, it won’t trigger again as long as the ability is on the stack. If the ability is countered and the trigger condition is still true, it will immediately trigger again. If the ability resolves, you’ll have to sacrifice Phyrexian Devourer even if its power has been reduced to 6 or less by then.

    Abilities/Keywords

    Suspend

    Rules

  • If your life total is less than or equal to the life total of the opponent with the most life, Roiling Horror's toughness is 0 or less. It will be put into its owner's graveyard as a state-based action.
  • You never choose an opponent, and the opponent that Roiling Horror looks at is never "locked in." Roiling Horror continuously looks at the life totals of all opponents and uses whichever value is the largest.
  • A creature cast using suspend will enter the battlefield with haste. It will have haste until another player gains control of it. (In some rare cases, another player may gain control of the creature spell itself. If this happens, the creature won't enter the battlefield with haste.)
  • Cards exiled with suspend are exiled face up.
  • Due to a recent rules change to suspend, you are no longer required to cast the suspended card as the second triggered ability of suspend resolves. Instead, as the second triggered ability resolves, you may cast the card. Timing permissions based on the card's type are ignored. If you don't cast the card, it remains exiled with no time counters on it, and it's no longer suspended.
  • Exiling a card with suspend isn't casting that card. This action doesn't use the stack and can't be responded to.
  • If an effect refers to a "suspended card," that means a card that (1) has suspend, (2) is in exile, and (3) has one or more time counters on it.
  • If the card has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.
  • If the first triggered ability of suspend (the one that removes time counters) is countered, no time counter is removed. The ability will trigger again at the beginning of the card's owner's next upkeep.
  • If the second triggered ability is countered, the card can't be cast. It remains exiled with no time counters on it, and it's no longer suspended.
  • If the spell requires any targets, those targets are chosen when the spell is finally cast, not when it's exiled.
  • If this is suspended, then when the last time counter is removed from it, both its triggered ability and the "you may cast this spell" part of the suspend ability will trigger. They can be put on the stack in either order.
  • If you cast a card "without paying its mana cost," such as with suspend, you can't choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, you must pay those if you want to cast the card.
  • Suspend is a keyword that represents three abilities. The first is a static ability that allows you to exile the card from your hand with the specified number of time counters (the number before the dash) on it by paying its suspend cost (listed after the dash). The second is a triggered ability that removes a time counter from the suspended card at the beginning of each of your upkeeps. The third is a triggered ability that gives you the option to cast the card when the last time counter is removed.
  • The mana value of a spell cast without paying its mana cost is determined by its mana cost, even though that cost wasn't paid.
  • When the last time counter is removed, the second triggered ability of suspend (the one that lets you cast the card) triggers. It doesn't matter why the last time counter was removed or what effect removed it.
  • You can exile a card in your hand using suspend any time you could cast that card. Consider its card type, any effects that modify when you could cast it (such as flash) and any other effects that stop you from casting it (such as from Meddling Mage's ability) to determine if and when you can do this. Whether you could actually complete all steps in casting the card is irrelevant. For example, you can exile a card with suspend that has no mana cost or that requires a target even if no legal targets are available at that time.

    Roiling Horror's power and toughness are each equal to your life total minus the life total of an opponent with the most life. Suspend X—. X can't be 0. (Rather than cast this card from your hand, you may pay and exile it with X time counters on it. At the beginning of your upkeep, remove a timecounter When the last is removed, you may cast it without paying its mana cost. It has haste.) Whenever a timecounteris removed from this card while it's exiled, target player loses 1 life and you gain 1 life.
