Flying {T}: Add one mana of any color.

{T}: Add {C}. {T}: Add one mana of any color. Spend this mana only to cast a legendary spell, and that spell can't be countered.

If one or more -1/-1 counters would be put on a creature you control, that many -1/-1 counters minus one are put on it instead.

{T}: Add {G}. Put a -1/-1 counter on this creature: Untap this creature.

Flash Reach When this creature enters, up to one target player puts all the cards from their graveyard on the bottom of their library in a random order. Evoke—Exile a green card from your hand.

If this card is in your opening hand, you may begin the game with it on the battlefield. Whenever you tap a creature for mana, add an additional {G}. {6}{G}{G}: Put a +1/+1 counter on each creature you control.

({B/P} can be paid with either {B} or 2 life.) Return target creature card with mana value X from your graveyard to the battlefield. It gains haste. Exile it at the beginning of the next end step.

Search your library for a green creature card with mana value X or less, put it onto the battlefield, then shuffle. Shuffle Green Sun's Zenith into its owner's library.

Search your library for a creature card with mana value X or less, put it onto the battlefield, then shuffle. Harmonize {X}{G}{G}{G}{G} (You may cast this card from your graveyard for its harmonize cost. You may tap a creature you control to reduce that cost by an amount of generic mana equal to its power. Then exile this spell.)

As long as Grist isn't on the battlefield, it's a 1/1 Insect creature in addition to its other types. +1: Create a 1/1 black and green Insect creature token, then mill a card. If an Insect card was milled this way, put a loyalty counter on Grist and repeat this process. −2: You may sacrifice a creature. When you do, destroy target creature or planeswalker. −5: Each opponent loses life equal to the number of creature cards in your graveyard.

You may activate abilities of creatures you control as though those creatures had haste. +1: Untap up to one target creature. −2: Mill three cards, then you may return a creature card with mana value 2 or less from your graveyard to the battlefield.
