Whenever you put one or more counters on a permanent or player, All Will Be One deals that much damage to target opponent, creature an opponent controls, or planeswalker an opponent controls.

Flying

Whenever Flameblast Dragon attacks, you may pay {X}{R}. If you do, Flameblast Dragon deals X damage to any target.

Until end of turn, target creature gets +3/+3 and gains trample and "Whenever this creature deals combat damage to a player, draw that many cards."

Trample

When Pelakka Wurm enters the battlefield, you gain 7 life.

When Pelakka Wurm dies, draw a card.

Extort (Whenever you cast a spell, you may pay {W/B}. If you do, each opponent loses 1 life and you gain that much life.)

Other creatures you control have extort. (If a creature has multiple instances of extort, each triggers separately.)

Indestructible

Whenever Predator Ooze attacks, put a +1/+1 counter on it.

Whenever a creature dealt damage by Predator Ooze this turn dies, put a +1/+1 counter on Predator Ooze.

Search your library for a basic land card, put that card onto the battlefield tapped, then shuffle.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after IV.)

I -- Create a 1/1 white Human Soldier creature token.

II -- Put three +1/+1 counters on target creature you control.

III -- If you control a creature with power 4 or greater, draw two cards.

IV -- Create a Gold token. (It's an artifact with "Sacrifice this artifact: Add one mana of any color.")

Whenever another creature enters the battlefield under your control, you gain life equal to that creature's toughness.

{1}{G}{W}, {T}: Populate. (Create a token that's a copy of a creature token you control.)

As an additional cost to cast this spell, sacrifice a creature.

Draw two cards.

{T}, Sacrifice two creatures: Return target creature card from your graveyard to the battlefield.
