At the beginning of your upkeep, you may discard a land card. When you do, create a 2/2 green Wolf creature token.

Whenever you play a land, you may search your library for a land card that shares a subtype with it, put it onto the battlefield tapped, then shuffle.

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.)

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.

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.'”

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
When Budding Companion has three or more +1/+1 counters on it, remove them all and transform it.

Create a 3/2 green Horror creature token.
Reconstruct {4}{G} (You may cast this from your graveyard for its reconstruct cost reduced by the mana value of a permanent you sacrifice as you cast it this way. Then exile this.)

{T}, Sacrifice a creature: Investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)
{T}, Sacrifice a Clue: Create a 3/3 green Elemental creature token.

Converge — Destroy up to X target artifacts or enchantments, where X is the number of colors of mana spent to cast Bury the Past.

Target creature gets +4/+2 and gains trample until end of turn.

Foretell {1}{G}{G} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)
Choose one. If this spell was foretold, you may choose both instead —
• Create two tapped 1/1 white Peasant creature tokens.
• You gain 7 life.

When Cabinet of Curiosities enters, create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)
If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.

When Caer Crann Borderscout enters, you may search your library for a basic land card, reveal it, and put it into your hand. If you do, shuffle.

When Caer Crann Warleader enters, distribute three +1/+1 counters among any number of creatures you control.
Embattled creatures you control have trample. (A creature is embattled if it has a counter on it or a permanent you control attached to it.)

Target creature or planeswalker you control explores. (Reveal the top card of your library. Put it into your hand if it's a land. Otherwise, put a +1/+1 or loyalty counter on that permanent, then you may put that card into your graveyard.)

This spell can't be countered.
Search your library for a basic land or a Hydra card not named Aurora Hydra, reveal it, and put it into your hand. Then shuffle.

Recruit. (Create a 0/0 white Soldier Army creature token, then put a +1/+1 counter on each Army you control.)
Armies you control gain trample until end of turn.

Create a 1/1 colorless Construct Actor creature token. Put a +1/+1 counter on it if you control another Construct.
Compose (Then if you cast this from your hand, exile it and create a Saga token with “r3—You may cast a copy of this card from exile without paying its mana cost.”)

Sacrifice a permanent, then draw cards equal to its mana value.
You may put a permanent card from your hand onto the battlefield if its mana value is less than or equal to the number of cards in your hand.

Destroy up to one target creature with flying or enchantment. Create an Idol token. (It's an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

{1}{G}{G}, Sacrifice a creature: Search your library for a creature card with mana value X or less, where X is 1 plus the sacrificed creature's mana value. Put that card onto the battlefield, then shuffle. Activate only as a sorcery.

Archive 3 (As this enters, shuffle the top three cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever you draw a card from the archived library, put the top card of your main library on the bottom of the archived library.
{G}: Exchange a card from the archived library with a card from your hand.

{T}, Sacrifice Camahueto Calf: Return target land card from your graveyard to the battlefield.

This spell costs {1} less to cast for each creature you control.
