Deep-Sea Terror can't attack unless there are seven or more cards in your graveyard.

Target player reveals their hand. You choose a nonland card from it. Exile that card.

Instead of taking turns as normal, players take their phases sequentially. (For example, you take your beginning phase as the active player, then the next player in turn order becomes the active player and takes their beginning phase. After each player had a beginning phase, do the same for first main, combat phase, second main, ending phase, and then beginning phase again. If this creature leaves the battlefield, the active player continues their turn as normal.)

Flying, trample

Stingerback Terror gets -1/-1 for each card in your hand.

Plot (You may pay and exile this card from your hand. Cast it as a sorcery on a later turn without paying its mana cost. Plot only as a sorcery.)

Menace

Whenever Terror Ballista attacks, you may sacrifice another creature. When you do, destroy target creature an opponent controls.

Unearth (: Return this card from your graveyard to the battlefield. It gains haste. Exile it at the beginning of the next end step or if it would leave the battlefield. Unearth only as a sorcery.)

Flying

Double strike (This creature deals both first-strike and regular combat damage.)

When this creature enters, creatures you control gain double strike until end of turn.

Flying

Spells your opponents cast that target Terror of the Peaks cost an additional 3 life to cast.

Whenever another creature you control enters, Terror of the Peaks deals damage equal to that creature's power to any target.

Fathomless descent — All creatures get -X/-X until end of turn, where X is the number of permanent cards in your graveyard.

Whenever Tidal Terror attacks, you may tap two other untapped creatures you control. If you do, Tidal Terror can't be blocked this turn.

Islandcycling (, Discard this card: Search your library for an Island card, reveal it, put it into your hand, then shuffle.)

Flying, lifelink

Ward—Sacrifice three nonland permanents.

If a card you didn't control would be put into an opponent's graveyard from anywhere, exile it instead.

During your turn, you may play cards exiled with Valgavoth. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost.
