Maro

Maro's power and toughness are each equal to the number of cards in your hand.

Mindbender Spores

Defender (This creature can't attack.)
Flying
Whenever this creature blocks a creature, put four fungus counters on that creature. The creature gains "This creature doesn't untap during your untap step if it has a fungus counter on it" and "At the beginning of your upkeep, remove a fungus counter from this creature."

Ivory Charm

Choose one —
• All creatures get -2/-0 until end of turn.
• Tap target creature.
• Prevent the next 1 damage that would be dealt to any target this turn.

Mtenda Lion

Whenever this creature attacks, defending player may pay {U}. If that player does, prevent all combat damage that would be dealt by this creature this turn.

Natural Balance

Each player who controls six or more lands chooses five lands they control and sacrifices the rest. Each player who controls four or fewer lands may search their library for up to X basic land cards and put them onto the battlefield, where X is five minus the number of lands they control. Then each player who searched their library this way shuffles.

Nettletooth Djinn

At the beginning of your upkeep, this creature deals 1 damage to you.

Preferred Selection

At the beginning of your upkeep, look at the top two cards of your library. You may sacrifice this enchantment and pay {2}{G}{G}. If you do, put one of those cards into your hand. If you don't, put one of those cards on the bottom of your library.

Quirion Elves

As this creature enters, choose a color.
{T}: Add {G}.
{T}: Add one mana of the chosen color.

Rampant Growth

Search your library for a basic land card, put that card onto the battlefield tapped, then shuffle.

Roots of Life

As this enchantment enters, choose Island or Swamp.
Whenever a land of the chosen type an opponent controls becomes tapped, you gain 1 life.

Sabertooth Cobra

Poison Counter

Whenever this creature deals damage to a player, that player gets a poison counter. The player gets another poison counter at the beginning of their next upkeep unless they pay {2} before that step. (A player with ten or more poison counters loses the game.)
