Exile up to three target cards from graveyards. (Then exile this card. You may cast the creature later from exile.)

Trample
Whenever another Dwarf you control enters, create a colorless artifact token named Ale. It has “{T}, Sacrifice this artifact: Target creature gets +2/+0 until end of turn. Activate only as a sorcery.”

Vigilance
Whenever Bartimus attacks, another target attacking creature gets +1/+1 until end of turn. If that creature is a Soldier, put a +1/+1 counter on it instead.

Return any number of target creature cards with total mana value X or less from your graveyard to the battlefield, where X is the number of cards in your graveyard. Exile Battle at the Boneyard.

Enchant creature you control
Enchanted creature gets +3/+3.
When Belligerence enters, enchanted creature fights target creature an opponent controls.
When enchanted creature dies, if it's a Warrior, return Belligerence to its owner's hand.

Reprise {4}{G} (As you cast an instant or sorcery spell, you may exile one card with reprise from your graveyard and pay its reprise cost. If you do, add its effects to that spell.)
Target creature gets +3/+3 until end of turn. Then create an X/X green Elk creature token, where X is the amount this spell increased that creature's power.

Aetherize each permanent you control. Exile Beneath the Horizon. (To aetherize a permanent, create a token that's a copy of it, then exile that token.)

Armed — Beragnian Blacksmith can't attack unless it's equipped.
When Beragnian Blacksmith enters, you may pay {2}. If you do, arm it. (Create a colorless Equipment artifact token with “Equipped creature gets +1/+0” and equip {2}, then attach it to this creature.)

Menagerie — This spell costs {2} less to cast if there are five or more creature types among creatures you control.
Destroy target creature with power or toughness 4 or greater.

Equipped creature gets +1/+1 and has haste.
Whenever a creature you control enters, if it was cast from exile, you may attach Blade of the Valiant to it.
Equip {2}

Blazing Outro deals 4 damage to any target. Then you may tap an untapped Wizard you control. If you do, cast an instant or sorcery card with mana value 4 or less from your graveyard without paying its mana cost. If it has {X} in its mana cost, X is 4. If that spell would be put into a graveyard, exile it instead.

Flying
Menagerie — When Bleakrealm Mini-Menace enters, if there are five or more creature types among creatures you control, it deals 2 damage to target opponent and 2 damage to up to one target creature or planeswalker that player controls.

Bleakrealm Moor enters tapped unless you played it from exile.
{T}: Add {B} or {R}.

Vigilance
Blessed Suncrusher's power and toughness are each equal to your life total.

{T}: Add {C}.

Bloodsand Gulch enters tapped unless you control another Desert.
{T}: Add {B} or {R}.

Blooming Needles enters tapped unless you control another Desert.
{T}: Add {R} or {G}.

You may pay {1}{B} and tap an untapped Shaman you control rather than pay this spell's mana cost.
Target player sacrifices a creature. You gain life equal to its toughness.

When Boundary Hallowblade enters, create a white Aura enchantment token named Consecration Blessing attached to target land. The token has enchant land and “Enchanted land is named Hallowed Ground and has indestructible.”

You may activate Boxue and Ma'Long's loyalty abilities an additional time if you've cast two or more spells this turn.
[+1]: Scry 2.
[–2]: Exile the top two cards of your library. You may play one of them this turn. When you do, put the other card into your hand.

Bristling Skoki has first strike as long as it's attacking.
Whenever Bristling Skoki blocks a creature, you may have it deal damage equal to its toughness to that creature.

Double strike
Whenever you cast a noncreature spell, you may choose one that hasn't been chosen —
• Tap or untap target permanent.
• Draw two cards, then discard a card.
• Creatures you control get +1/+1 until end of turn.

(Add a quest counter as this enters. Sacrifice after 3.)
1, 2 — Whenever you attack with exactly two creatures, add a quest counter.
3 — Reveal the top four cards of your library. You may put a creature card from among them into your hand. Put the rest on the bottom in a random order.
Put two +1/+1 counters on each of up to two target creatures you control.
