Indestructible
When Dark Behemoth dies, return another target creature card from your graveyard to the battlefield.

Mill five cards. You may choose up to two nonland cards with mana value 2 or less milled this way. You may cast one without paying its mana cost. Put the rest into your hand.
Coalesce {6}{G}{W} (You may cast this from your graveyard for {6}{G}{W}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)
Flying, vigilance

At the beginning of your end step, untap all lands you control. You may put three +1/+1 counters on target land you control. If you do, that land becomes a 0/0 Treefolk creature with haste that's still a land.

(Transcend as a sorcery to gain that type and a +1/+1 counter.)
{T}, Tap an untapped creature you control: Add one mana of any color.
{G}: Demigod — Whenever you cast a creature spell this turn, draw a card.
{4}{G}{G}: God — Creatures you control get +3/+3 and gain trample until end of turn.

Flying
When Illusionary Steed becomes the target of a spell or ability, sacrifice it.

Creatures you control attacking cause abilities of that creature to trigger as though it entered.
{2}{R}{W}: Target creature gains vigilance and haste until end of turn. After this main phase, there is an additional combat phase followed by an additional main phase.

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 in a random order.)
Flying
Dragon spells you cast have cascade.

As long as you control two or more other Pirates, Ragavan has haste.
Whenever one or more Pirates you control deal combat damage to a player, create a tapped Treasure token.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I — Return target creature card with mana value 2 or less from your graveyard to the battlefield.
II — Each opponent loses 2 life and you gain 2 life.
III — Return target creature card with mana value 2 or less from your graveyard to the battlefield.
