Gríma can't be blocked.
Whenever Gríma deals combat damage to a player, that player exiles cards from the top of their library until they exile an instant or sorcery card. You may cast that card without paying its mana cost. Then that player puts the exiled cards that weren't cast this way on the bottom of their library in a random order.

Flying
, : Target Faerie or Elf gains lifelink until end of turn. (Damage dealt by the creature also causes its controller to gain that much life.)

Choose two —
• Counter target spell.
• Return target permanent to its owner's hand.
• Tap all creatures your opponents control.
• Draw a card.

Return up to three target land cards from your graveyard to your hand.
Dredge 3 (If you would draw a card, you may mill three cards instead. If you do, return this card from your graveyard to your hand.)

When this creature enters, target creature an opponent controls gets -3/-3 until end of turn. If that creature is legendary, its controller loses 3 life.
When the Ring tempts you, return this card from your graveyard to your hand.

At the beginning of your upkeep, if you have 50 or more life, you win the game.

Kicker
Each opponent mills eight cards. If this spell was kicked, instead each opponent mills half their library, rounded up.

You may play an additional land this turn.
Draw a card.

You may pay rather than pay the mana cost for Zombie creature spells you cast.

Whenever a creature you control deals combat damage to a player, put a +1/+1 counter on that creature.
Unlock Ability — Creatures you control with +1/+1 counters on them have reach and trample.

Flying, vigilance, haste
Whenever Aurelia attacks for the first time each turn, untap all creatures you control. After this phase, there is an additional combat phase.

Search your library for up to two basic land cards, reveal those cards, put one onto the battlefield tapped and the other into your hand, then shuffle.

This spell costs less to cast, where X is the total toughness of creatures you control.
Defender
: Until end of turn, target creature you control gets +1/+0, gains "Whenever this creature deals combat damage to a player, draw cards equal to its toughness," and can attack as though it didn't have defender.

Each player discards their hand, then draws seven cards.
Miracle (You may cast this card for its miracle cost when you draw it if it's the first card you drew this turn.)

This land enters tapped.
: Add .

Put a -1/-1 counter on target creature, two -1/-1 counters on another target creature, and three -1/-1 counters on a third target creature.

You may pay rather than pay the mana cost for spells you cast.

Each creature spell you cast with mana value 4 or greater has blitz. The blitz cost is equal to its mana cost. (You may choose to cast that spell for its blitz cost. If you do, it gains haste and "When this creature dies, draw a card." Sacrifice it at the beginning of the next end step.)
Blitz costs you pay cost less for each time you've cast your commander from the command zone this game.

: Target player exiles a card from their graveyard.
, Exile this artifact: Exile all graveyards. Draw a card.
