At the beginning of each player's postcombat main phase, that player adds for each of your opponents who lost life this turn. (Damage causes loss of life.)

Note the converted mana cost of each card as it's put into exile.
Bell Borca, Spectral Sergeant's power is equal to the greatest number noted for it this turn.
At the beginning of your upkeep, exile the top card of your library. You may play that card this turn.

Each creature you control assigns combat damage equal to its toughness rather than its power.

First strike
Belligerent Hatchling enters the battlefield with four -1/-1 counters on it.
Whenever you cast a red spell, remove a -1/-1 counter from Belligerent Hatchling.
Whenever you cast a white spell, remove a -1/-1 counter from Belligerent Hatchling.

Islandwalk (This creature can't be blocked as long as defending player controls an Island.)
At the beginning of your upkeep, you lose 2 life.

A person outside the game becomes your teammate. (Choose any number of cards in your hand, on top of your library, or on the battlefield under your control. Those cards become your teammate's hand, library, and permanents, respectively.)

Trample
Bioessence Hydra enters the battlefield with a +1/+1 counter on it for each loyalty counter on planeswalkers you control.
Whenever one or more loyalty counters are put on planeswalkers you control, put that many +1/+1 counters on Bioessence Hydra.

Activated abilities of creatures you control cost less to activate. This effect can't reduce the mana in that cost to less than one mana.
: The next time target creature adapts this turn, it adapts as though it had no +1/+1 counters on it.

Draw a card for each creature target player controls, then draw a card for each creature another target player controls.

Creatures you control have base power and toughness X/X until end of turn.

Move any number of +1/+1 counters from target creature onto another target creature with the same controller.

At the beginning of the end step, if you control four or more creatures named Biovisionary, you win the game.

Cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom of your library in a random order.)
Bituminous Blast deals 4 damage to target creature.

Flying
When Bladewing the Risen enters the battlefield, you may return target Dragon permanent card from your graveyard to the battlefield.
: Dragon creatures get +1/+1 until end of turn.

Choose any target. Draw three cards, then discard a card. Blast of Genius deals damage equal to the discarded card's converted mana cost to that permanent or player.

Whenever an instant or sorcery spell you control deals damage, create two 1/1 red and white Soldier creature tokens with haste.

, Sacrifice another creature: Blazing Hellhound deals 1 damage to any target.

Flying, haste
Whenever Blazing Specter deals combat damage to a player, that player discards a card.

Blightning deals 3 damage to target player or planeswalker. That player or that planeswalker's controller discards two cards.

Flying
Whenever Blim, Comedic Genius deals combat damage to a player, that player gains control of target permanent you control. Then each player loses life and discards cards equal to the number of permanents they control but don't own.
