Indestructible
Marva of Endless Inspiration can't attack or block unless you've cast a spell with mana value 4 or greater this turn.

When Maw of a Thousand Worlds dies, you may remove any number of counters from among permanents you control. For each counter removed this way, draw a card.

Create X 1/1 black Goblin creature tokens. Gain control of target permanent with mana value X or less until end of turn. Untap it. It gains haste until end of turn.

This spell can't be countered.
Whenever Meren, Bane of the Cairns attacks, exile target creature card from your graveyard. You may cast that card for as long as it remains exiled by sacrificing a creature in addition to paying its other costs.

Mianju enters the battlefield with your choice of a menace or +1/+1 counter on them.
Whenever two or more creatures in Mianju's pack attack, mill three cards, then return a creature card from your graveyard to your hand. (Two or more creatures you control with equal power are in a pack.)

At the beginning of your end step, you may mill two cards. If you do, you gain 2 life.
[+1]: You may discard a card. If you do, draw a card.
[–2]: Exile up to six cards from your graveyard. Create a 1/1 red and green Spirit creature token for each two cards exiled this way.

At the beginning of your end step, create a Gold token for each creature you controlled that became tapped this turn. (It's an artifact with “Sacrifice this artifact: Add one mana of any color.”)

Whenever another nontoken creature you control dies, you may exile it. If you do, create a token that's a copy of it, except it has base power and toughness 1/1. If that creature had power 4 or greater, create two of those tokens instead.

Exile target creature. That creature's controller reveals cards from the top of their library until they reveal a creature card. That player puts that card onto the battlefield, then shuffles the rest into their library. If you own that card, it enters the battlefield with an additional X +1/+1 counters on it, where X is its power.

Whenever you activate an ability of a creature that isn't a mana ability, Moranai Tracker gets +1/+1 until end of turn.

Whenever you cast a spell with mana value greater than the number of lands you control, sacrifice a land.

Whenever you cast an instant or sorcery spell, create a 3/1 red Sand creature token with haste.
Whenever you cast an enchantment or artifact spell, create a 2/2 blue Sand creature token with hexproof.
Whenever a land enters the battlefield under your control, create a 3/3 green Sand creature token.

• Target player searches their library for up to two basic land cards, reveals those cards, puts one onto the battlefield tapped and the other into their hand, then shuffles.
• Target creature you control fights target creature you don't control.
• Target player gains 5 life.

This spell costs {X} less to cast, where X is the greatest power among creatures you controlled that died this turn.
