When a creature you control becomes the target of a spell or ability an opponent controls, sacrifice Bestial Harmony. If you do, draw three cards.

Create a 3/3 green Beast creature token, then populate. (Create a token that's a copy of a creature token you control.)

Exile target card from a graveyard. Create a 1/1 black Worm creature token.
Fuse (You may cast one or both halves of this card from your hand.)

As an additional cost to cast this spell, remove X +1/+1 counters from among creatures you control.
Create X 2/2 green Wolf creature tokens.

Create two tapped colorless land tokens named Far-Off Lands with “{T}: Add one mana of any color.” (Then exile this card. You may cast the creature later from exile.)

Pressure {2}{G} (You may cast this spell for its pressure cost if seven or more cards are in your graveyard.)
As an additional cost to cast this spell, sacrifice a creature.
Search your library for a creature card with mana value X or less, where X is equal to twice the sacrificed creature's mana value, put it onto the battlefield, then shuffle.

Until end of turn, cards in graveyards lose all names, card types, and abilities.
Draw a card.

Put a +1/+1 counter on each of up to X target creatures.

Invigorate X, where X is the number of creatures you control. (Choose a creature with the least power among creatures you control and put X +1/+1 counters on it.)

Whenever enchanted land is tapped for mana, its controller adds two mana in any combination of colors (in addition to the mana the land produces.)

Distribute three +1/+1 counters among one, two, or three target creatures you control.

Put a +1/+1 counter on target creature you control.

Look at the top four cards of your library. You may reveal a permanent card from among them and put it into your hand. Put the rest on the bottom of your library in any order.

Destroy target artifact or enchantment. If that permanent was a token, proliferate. (Choose any number of permanents and/or players with counters on them, then give each another counter of each kind already there.)

Target creature you control gets +2/+2 and gains hexproof until end of turn.

Bound by Nature enters with X nature counters on it.
You can't cast nonpermanent spells.
Creatures you control get +1/+1 for each nature counter on Bound by Nature and have “{T}: Add {G}.”
