Whenever you cast an artifact spell, create a 1/1 colorless Construct artifact creature token.

Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter on it and it becomes renowned.)

Target creature you control deals damage equal to its power to target creature you don't control.
Whenever a creature you control with deathtouch deals damage to an opponent, you may sacrifice that creature. If you do, return Shedding of the Coils from your graveyard to your hand.

If you would draw one or more cards, draw that many cards plus one instead.
When Unleashed Mindboggler dies, return it to the battlefield (front face up).

Counter target creature spell, planeswalker spell, or activated ability.

{1}, {T}: Copy target activated or triggered ability you control. You may choose new targets for the copy.
{3}{U}, {T}: Copy target spell you control. You may choose new targets for the copy. (A copy of a permanent spell becomes a token.)

Manifest the bottom X cards of your library tapped, where X is the number of instant and sorcery cards in your graveyard. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

Shimmer (Whenever this creature attacks, create a tapped and attacking token that's a copy of it. Exile the token at the beginning of the end step.)

Target creature gets +1/+0 and gains first strike and haste until end of turn.

Wu Xing (Add effects based on the number of colors of mana spent to cast this spell.)
1 | Return to the battlefield up to X target nonland permanent cards from your graveyard that were put there from the battlefield this turn.
5 | If a permanent entering the battlefield causes an ability of a permanent you control to trigger this turn, that ability triggers an additional time.

Whenever Slyten Connoisseur attacks, crystallize. (Put a +1/+1 counter on a creature you control or create a Treasure.)
Once each turn, when an artifact you control dies, you may pay 1 life. If you do, draw a card.

{T}: Add {C}.
{T}, Sacrifice Shiftscape Grove: Choose a basic land type other than Forest. Create a colorless land token that's a Forest and the chosen basic land type. Activate only during your upkeep.

Choose one —
• Destroy each creature with mana value 2 or less.
• Destroy each noncreature, nonland permanent with mana value 2 or less.

Counter target spell.
Create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)

When Ruins Entrance enters, exile up to three target cards from graveyards.
{1}, {T}: Exile target card from a graveyard.
{5}, {T}, Sacrifice Ruins Entrance: Return target card from your graveyard to your hand.

Sacrifice Indomitable Bear: Creatures you control gain indestructible until end of turn.

At the beginning of combat on your turn, create a 1/1 white Human creature token.
Creature tokens you control have haste and attack each combat if able.
{1}{W}: Transform Charging Commando. Activate only if two or more creatures that attacked this turn died under your control this turn.

Flying
Wailing Soul has hexproof as long as it's not attacking or blocking.

Vigilance
Creatures you control with a +1/+1 counter on them have mentor. (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)
Creatures you control with no +1/+1 counters on them have training. (Whenever this creature attacks with another creature with greater power, put a +1/+1 counter on this creature.)

Enchant noncreature permanent
Enchanted permanent is a colorless Forest land. (It has “{T}: Add {G}.”)

When Pre-Crime Handler enters, conjure a card named Data-Point into your hand. You gain 2 life. (It's a sorcery that costs {2} with “Draw a card.”)

Flying
As long as you control exactly one other creature, that creature gets +1/+1 and has flying.

Target player discards a card and loses 2 life.
Draw a card.

{1}{G}, Discard a card: Target land you control becomes a 3/3 Elemental creature. It's still a land. Exile the top card of your library face down.
Whenever a land creature you control deals combat damage to a player, put a card exiled with Children of Gos into your hand.
