Whenever Elvish Wayfinder enters or attacks, reveal the top four cards of your library. You may put a land card that doesn't share a name with a land you control into your hand. Put the rest on the bottom of your library in any order.

As this permanent transforms into Velir, put four loyalty counters on it.
[+1]: Draw two cards, then discard two cards unless you discard a land card.
[–2]: Search your library for a multicolored card, reveal it, put it into your hand, then shuffle.
[–4]: Exile target permanent.

When El, Humble Apprentice enters, search your library for a basic land card, reveal it, put it into your hand, then shuffle.
Chosen one ({W}{U}{B}{R}{G}: Transform this permanent.)

Escalate {G} (Pay this cost for each mode chosen beyond the first.)
Choose one or more —
• Target creature gets +3/+2 until end of turn.
• Target creature gains trample and hexproof until end of turn.

Whenever a creature you control dies, you may search your library for a creature card with lesser mana value, put it onto the battlefield tapped, then shuffle. Do this only once during each of your turns.

Trample
Chronicle (As this enters and after your draw step, add a lore counter. Stop after III.)
[Lore I-II] Creatures you control gain vigilance until end of turn.
[Lore III] Remove all lore counters from Astral Leucrocota. You gain 4 life.

This spell costs {1} less to cast for each differently named land you control.
Reach, trample

Improve {1} ({1}: Put a +1/+1 counter on this creature. This costs {1} more to activate for each +1/+1 counter on it. Improve only as a sorcery.)
Once each turn, when one or more counters are put on a permanent you control, create a 1/1 colorless Human creature token.
Whenever you attack with three or more creatures, destroy up to one target artifact or enchantment.

{T}: Add one mana of any type that a land an opponent controls could produce.

Voidflare deals 2 damage to any target.
Wanderlust — Voidflare deals 3 damage instead if you control four or more differently named lands.

Whenever you cast a spell that targets, put a loyalty counter on Valeri Kripac and create a 1/1 white Soldier creature token.
[+1]: Add {R}. If you spend this mana on a spell that targets, that spell can't be countered.
[–2]: Exile target instant or sorcery card from your graveyard. You may play it until the end of your next turn. If you do, exile that spell instead of putting it anywhere else.

Volcanic Rain deals damage to target creature or planeswalker equal to the number of lands you control.

Flying
Ward—Pay 3 life.
Landfall — Whenever a land you control enters, Valakut Hellkite deals 3 damage to any target.

(Transform this if it's not attached to a creature. Pay {1}{R} as a sorcery to unattach it.)
Enchant creature you control
Scale Bearer's rider gets +4/+3 and has flying and haste.
Whenever Scale Bearer's rider attacks, you may pay {2}{R}. If you do, it deals damage equal to its power to target creature or planeswalker.

Flying, haste
Ride {1}{R} ({1}{R}: Transform this and attach it to target creature you control without a Mount. Ride only as a sorcery.)

Haste
Motley — At the beginning of your upkeep, if there are five or more names among nonland permanents you control, Scarletblood Hound deals 3 damage to each opponent.

{T}: Target creature gains haste until end of turn.
{1}{R}, {T}, Sacrifice a Human: Create a token that's a copy of the sacrificed creature, except it's a 3/2 colorless Horror. It gains haste until end of turn. Activate only as a sorcery.

Choose two or four —
• Each opponent sacrifices an artifact.
• Create a 1/1 red Warrior creature token.
• Creatures you control get +1/+0 and gain trample and haste until end of turn.
• Conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

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.

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.

Search your library for a Dragon card, reveal it, put it into your hand, then shuffle. It deals damage equal to its power to you.

Ominous Dragoncaller gets +1/+1 and has flying as long as you control a Dragon.

Once each turn for each card type, when you cast a spell with that type, you may copy it. You may choose new targets for the copy. If it's a permanent spell, the copy gains haste and “At the beginning of the end step, sacrifice this permanent.”
Whenever a permanent you control dies, it deals 1 damage to each opponent.

Choose one —
• Fuel for the Fire deals 5 damage to target creature or planeswalker. Its controller creates a tapped Treasure token. If a permanent dealt damage this way would die this turn, exile it instead.
• Exile target artifact. Its controller creates a tapped Treasure token.

Fires of Renewal deals 2 damage to each creature.
Create a Treasure token.
