Search your library for up to two basic land cards and put them onto the battlefield tapped, then shuffle.
Fuse (You may cast one or both halves of this card from your hand.)

Draw a card. (Cast a copy of this spell once while this creature is on the battlefield.)

{U/B}{U/B}: Return Nherix, the Soulcage from your graveyard to the battlefield tapped.

{1}, {T}: End the turn. Activate only during your turn.

Changeling (This card is every creature type.)
This creature enters with four -1/-1 counters on it.
Whenever another creature you control enters, if that creature has greater power or toughness than this creature, remove a -1/-1 counter from this creature.

Lifelink
Whenever you cast a noncreature spell, put a +1/+1 counter on Ch'aska Walla Vanguard.

Choose one —
• Fatefire deals X damage to target creature. It loses indestructible until end of turn.
• Fatefire deals 2 damage to each creature if X is 2. Creatures dealt damage this way lose indestructible until end of turn.

Target creature gets +2/+2 and gains lifelink until end of turn.

Whenever a creature you control is dealt damage, put a +1/+1 counter on that creature.

Vanguard's Assault deals X damage divided as you choose among any number of target creatures, where X is the number of attacking creatures.

Flash
Improve {W} ({W}: 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.)
You may activate equip and improve abilities any time you could cast an instant.

Create two 1/1 white Cleric creature tokens with lifelink.

Menace
Whenever you cast a glitched spell, Null Entity gets +2/+0 until end of turn for each time that spell was glitched.

Return up to one target creature or planeswalker card with mana value 3 or less from your graveyard to the battlefield. Creatures you control get +1/+1 until end of turn.

Vigilance
Invocation — Whenever you spend four or more mana to cast a spell or activate an ability during your turn, you gain 2 life.

As Precursor Gate leaves the battlefield, you may exile it. When you do, destroy target nonland permanent.

Dawn Hill Swiftstriker gets +2/+0 as long as you control another Warrior.

Enchant creature

Flying, deathtouch

Choose three. You may choose the same mode more than once.
• Return target creature with mana value 2 or less to its owner's hand.
• Scry 1, then draw a card, then discard a card.
• Target creature gets -2/-0 until end of turn and attacks this turn if able.

Motivate 2 (When this creature enters, you may motivate target creature with less power than this by putting two +1/+1 counters on it.)

As long as you've gained life this turn, Bloodied Outcast gets +1/+0 and has lifelink.
As long as an opponent has lost life this turn, Bloodied Outcast gets +0/+1 and has deathtouch.

Destroy target creature. If an opponent lost life this turn, that creature's controller mills five cards.

Forgotten Experiment can't be blocked.

Whenever you cast a legendary spell, each opponent loses 1 life and you gain 1 life.
