Indestructible
Whenever Cyrukan attacks, choose one —
• Create a Treasure token. (It's an artifact with “{T}, Sacrifice this artifact: Add one mana of any color.”)
• Create a Weapon token and attach it to target creature you control. (It's an Equipment artifact with equip {2} and “Equipped creature gets +1/+1.”)
At the beginning of each end step, if you control three or more tokens, transform Cyrukan.

({T}: Add {R} or {G}.)
As Dangerous Territory enters the battlefield, you may pay {1}. If you don't, Dangerous Territory enters the battlefield tapped.

Augmented — When Dead End Adventurer enters the battlefield, if you've spent {W}{U}{B}{R}{G} to cast spells this turn, destroy target creature you don't control.

As long as it's your turn, Defect 37 is a 7/7 Vehicle artifact with crew 2.
[+1]: Creatures and Vehicles you control get +1/+1 until end of turn.
[–1]: Put target permanent into its owner's library, third from the top. If Defect 37 is on the battlefield, return her to her owner's hand.
[–6]: Until end of turn, each noncreature, nonland permanent you control becomes a creature in addition to its other types with base power and toughness each equal to their mana value or base power, whichever is greater.

{T}: Add {C}.
{3}{R}: Until end of turn, Defect's Precinct becomes a 3/3 creature. It's still a land. It has trample if {G} was spent to activate this ability, has vigilance if {W} was spent, and has hexproof if {U} was spent.

Augmented — At the beginning of each end step, if you've spent {W}{U}{B}{R}{G} to cast spells this turn, put a +1/+1 counter on Defected Explorer.

Whenever Defective Abomination attacks, you may sacrifice a permanent. If you do, put a +1/+1 counter on it. It gains indestructible until end of turn.

Descended Gorge enters the battlefield tapped.
{T}: Add {R} or {G}.
Morph {2} (You may cast this card face down as a 2/2 creature for {3}. Turn it face up any time for its morph cost.)

Sacrifice a land: Desperate Ravager gets +2/+0 and gains haste until end of turn.

Search your library for a basic land card, put that card onto the battlefield tapped, then shuffle. Disastrous Sirocco deals damage to target creature equal to the number of lands you control.

{4}, {T}: Add {W}{U}{B}{R}{G}.

When Div of Bonded Souls enters the battlefield, create a 1/1 colorless Illusion creature token with “This creature is every creature type.”
Whenever a creature you control attacks, it gets +1/+0 until end of turn for each other attacking creature that shares a creature type with it.

Haste
When Doomed Alchemist dies, create two Treasure tokens. (They're artifacts with “{T}, Sacrifice this artifact: Add one mana of any color.”)

Vigilance
Whenever an opponent casts a spell, create a Treasure token unless that player pays {1}, then create a 1/1 white Merfolk creature token unless that player pays {1}.
{W}{U}{B}{R}{G}, {T}: Other creatures you control get +3/+3 and gain vigilance and indestructible until end of turn.

Vanishing 3 (This permanent enters the battlefield with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
Remove a time counter from Dwindling Stores: Add one mana of any color.

{1}{R}: Earnest Labourer gets +2/+0 until end of turn.
{4}{G}: Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

When Earthbreaker Behemoth enters the battlefield, it deals damage equal to its power to up to one target creature you don't control. Excess damage is dealt to that creature's controller instead.

At the beginning of each combat, you may have Elderin, Crystalline Crusader become a copy of another target creature you control with mana value 3 or less until end of turn, except its name is still Elderin, Crystalline Crusader, it's still 3/3, still legendary, and it's an artifact in addition to its other types.
{W}{U}{B}{R}{G}: Elderin gets +3/+3 until end of turn.

Defiance (Whenever this creature takes damage, if it survives and wasn't defiant, put a +1/+1 counter on it and it becomes defiant.)
{4}{R}: Elvish Verseblade deals 1 damage to each creature. Activate only as a sorcery.

Defender, reach
{T}, Discard a card: Create a 0/2 red and green Scarecrow creature token with defender and reach.
{R}{G}, {T}: Embergourd Scarecrow deals X damage to target player or planeswalker, where X is the number of creatures with defender you control.

Gestalt (When this or another creature enters under your control, you may merge it with the one in play, keeping counters and attachments. They become the permanent on top plus all abilities from under it.)
When this creature dies, it deals X damage to target player or planeswalker, where X is the number of cards and tokens merged with it.

Trample
Assault {2}{R}{G} (Whenever this attacks, if it has no +1/+1 counters on it, you may pay its assault cost to put a +1/+1 counter on it.)
If one or more +1/+1 counters would be put on a creature you control, that many plus one +1/+1 counters are put on it instead.

[+1]: Emperor Tzhai deals 1 damage to each creature, planeswalker, and opponent you don't control.
[0]: Target creature can't attack you or Emperor Tzhai until Emperor Tzhai leaves the battlefield.
[–10]: You control target player.

Whenever you cast a spell, draw X cards, where X is Enai, Who Wanders Alone's power.
As long as there are no other untapped creatures on the battlefield, Enai's power and toughness are switched.

Flying
Augmented — Whenever you cast a spell, if you've spent {W}{U}{B}{R}{G} to cast spells this turn, put a +1/+1 counter on Enlightened Guardian. It loses this ability and gains “Whenever this creature attacks, draw two cards.”
