Create two 1/1 green Insect creature tokens. (Cast a copy of this spell once while this creature is on the battlefield.)

Flash
Whenever you cast your second spell each turn, put a +1/+1 counter on Brooding Replacement.

Two target creatures you control each get +2/+1 until end of turn.

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.)
Whenever you attack with exactly two creatures, add a quest counter.
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.

This spell costs {1} less to cast for each artifact and/or enchantment you control.

{6}{U}: Brume Trench-Thrasher can't be blocked this turn. This ability costs {1} less to activate for each instant and sorcery card you own in exile and in your graveyard.

Ward {2}
Whenever Brunig enters or attacks, you may shuffle a card you own from outside the game into your library. If you do, you gain 2 life.
Brunig gets +2/+2 and has trample as long as your library contains at least forty cards more than the minimum deck size.

Target creature gets +0/+3 until end of turn. Whenever that creature perseveres this turn, draw a card. (A creature perseveres when it survives damage.)

Reach
Hexproof (This creature can't be the target of spells or abilities your opponents control.)

Whenever a creature you control becomes the target of a spell or ability, counter it unless its controller pays {1}. Whenever they do, put a +1/+1 counter on Brushcover Elf. (This includes your spells and abilities.)

Brushfire deals 3 damage to target creature. If that creature would die this turn, exile it instead.

Destroy target artifact.
Reprise {R} (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.)

Glorious end — When Brutal Champion dies, if it was tapped, each opponent sacrifices a creature.

Choose target creature. Brutal Descent deals 2 damage to each creature other than the chosen creature.
Ferocious — If the chosen creature has power 4 or greater, Brutal Descent deals 4 damage to each creature other than the chosen creature instead.

Flying
You may reveal the second card you draw each turn as you draw it. Whenever you reveal a nonland card this way, copy that card. You may cast the copy. If you don't, Brutal Director deals 2 damage to any target. (You still pay the spell's cost.)

Destroy target creature. Its controller discards a card.

Attacking creatures get +3/+0 until end of turn.

Brutal Struggle deals 2 damage to any target. Put a +1/+1 counter on up to one target creature.

Whenever one or more creatures you control deal combat damage to a player, you may destroy target artifact or enchantment that player controls.
Whenever you cast a green creature spell, create a 3/3 green Wurm creature token with trample.

Target opponent sacrifices a creature.
Rerun (If you cast this from your hand, exile it as it resolves. Whenever a creature you control dies, you may cast this card from exile without paying its mana cost.)

Target creature gets +3/+3 until end of turn.

Whenever another creature enters, Brutish Champion fights that creature.

Concord — Whenever Bubbledome Captain attacks, if there are four or more card types among permanents you control, each other attacking creature gets +1/+1 until end of turn.

When Bubbledome Chorister enters, create a green Aura enchantment token named Sanctum's Gift attached to target creature. The token has enchant creature and “Enchanted creature has ‘{T}: Add {G} for each enchanted creature you control.'”
