Creature spells you cast cost {1} less to cast.
Whenever you cast a creature spell, Bellowing Thoctar gets +2/+2 until end of turn.

Gestalt (When this or another creature you control enters, you may merge it with the one in play, keeping counters and attachments. They become the permanent on top plus all abilities from under it.)
This permanent gets +2/+2 for each card and token merged with it.

If you would draw a card, you may instead choose creature or land and exile cards from the top of your library until you exile a card of the chosen kind. Put that card into your hand and put all other cards exiled this way on the bottom of your library in a random order.

Flying
Whenever a permanent you control becomes the target of a spell or ability you don't control, choose one —
• Create a 3/3 red Manticore creature token.
• Create two Treasure tokens.
• Draw a card.

When Charming Marauder enters, you may destroy target artifact or enchantment.
Recite {2}{W} (You may cast this creature from your graveyard for its recite cost. If you do, exile it when it enters or if it would leave the battlefield.)

Indestructible
Whenever Cyrukan attacks, choose one —
• Create a Treasure token. (It's an artifact with “{T}, Sacrifice this artifact: Add one mana of any color.”)
• Create a Weapon token and attach it to target creature you control. (It's an Equipment artifact with equip {2} and “Equipped creature gets +1/+1.”)
At the beginning of each end step, if you control three or more tokens, transform Cyrukan.

Search your library for a basic land card, reveal it, put it into your hand, then shuffle. (Then exile this card. You may cast the creature later from exile.)

When Div of Bonded Souls enters, create a 1/1 colorless Illusion creature token with “This creature is every creature type.”
Whenever a creature you control attacks, it gets +1/+0 until end of turn for each other attacking creature that shares a creature type with it.

Dramatic Peril deals damage equal to the number of lands you control to any target. (Cast a copy of this spell once while this creatures is on the battlefield.)

Whenever Dunesea Dreadstalker or another nontoken creature you control dies, amass Soldiers 1. (Put a +1/+1 counter on an Army you control. It's also a Soldier. If you don't control one, create an 0/0 black Soldier Army creature token first.)

Search your library for a basic land card, put that card onto the battlefield tapped, then shuffle. Create three 1/1 Scout creature tokens that are all colors.

Trample
When Feral Devout enters, choose one —
• Put a +1/+1 counter on Feral Devout.
• Create a colorless artifact token named Lotus Petal with “{T}, Sacrifice this artifact: Add one mana of any color.”

Improve {R} ({R}: 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.)
Whenever another creature you control with power less than or equal to Folkvar, Galdurheim Brawler's power attacks, Folkvar deals 1 damage to the player or planeswalker that creature is attacking and you gain 1 life.

If a source you control would deal exactly 1 damage to a permanent or player, it deals 3 damage instead.

At the beginning of your upkeep, you may discard a card. If you do, draw a card.
{T}: You may put a creature card from your hand onto the battlefield. If you do, put a +1/+1 counter on that creature.

Vigilance, trample
Each creature you control can't have power less than its toughness. (If it would have less, it has as much as its toughness instead.)
Each creature your opponents control can't have toughness greater than its power.

Squirrels you control get +1/+0 and have haste.
Nonbasic lands your opponents control enter tapped.

Trample
Other Dwarves and Elves you control get +1/+1.
If Harl and Finn or another Dwarf or Elf you control entering the battlefield or attacking causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

Whenever you attack, you may pay {R}{W}. If you do, create a tapped and attacking token that's a copy of target attacking creature. Sacrifice the token at the beginning of the next end step.

[+2]: Until end of turn, up to one target creature you control gets +3/+3 and gains trample and vigilance.
[–2]: Destroy target artifact, enchantment, or tapped creature.

At the beginning of your upkeep, rouse 1. Then if you control a creature with power 5 or greater, put a +1/+1 counter on each creature you control. (Put a +1/+1 counter on a permanent you control. If it isn't a creature, tap it and it becomes a 0/0 creature in addition to its other types.)
