Destroy all nonland, nonenchantment permanents.
Spell mastery — If there are two or more instant and/or sorcery cards in your graveyard, you gain 2 life for each permanent destroyed this way.

{T}: Add {C}.
Concord — {T}: Create a Treasure token. Activate only if there are four or more card types among permanents you control.

Reprise {4}{U} (As you cast an instant or sorcery spell, you may exile one card with reprise from your graveyard and pay its reprise cost. If you do, add its effects to that spell.)
Target player mills a card. Create X tapped 2/2 black Zombie Pirate creature tokens, where X is the total number of cards milled by this spell.

Archive 5 (As this enters, shuffle the top five cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Encylopetia's power and toughness are each equal to the number of cards in the archived library.
At the beginning of your upkeep, exile a card from the archived library at random. You may play it this turn.

Each player discards their hand and sacrifices all permanents they control, draws seven cards, then abounds seven times. (To abound, you may cast a spell that costs less than this from your hand without paying its mana cost.)

As End of the Empire enters, choose a creature card name.
Whenever a creature you don't control with the chosen name dies, create a 4/4 colorless Demon Spirit creature token with menace.

As an additional cost to cast this spell, sacrifice a creature.
Create X Treasure tokens, where X is the sacrificed creature's mana value.

Destroy target creature. End of the Road deals damage equal to that creature's power to that creature's controller or a planeswalker that player controls.

Artifact creatures you control have haste.
At the beginning of your upkeep, create a 1/1 colorless Construct artifact creature token. If you control six or more artifacts, create a 6/6 colorless Golem artifact creature token instead. Tokens created this way attack this turn if able.

Destroy target creature or planeswalker.
Agonize (You may cast this card from your graveyard by putting a -1/-1 counter on a creature you control in addition to paying its other costs. Then exile this card.)

Whenever you cast a noncreature spell, create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)

Colossal 4—{4}{G}{G}{G} (You may cast this for its colossal cost to have it enter with four +1/+1 counters; or pay {4}{G}{G}{G} as a sorcery: Put four +1/+1 counters on it if it has none.)
Whenever a nontoken creature you control with a counter on it dies, create a 4/4 green Hydra creature token.

Whenever an Army you control dies, if it wasn't sacrificed, recruit. (Create a 0/0 white Soldier Army creature token, then put a +1/+1 counter on each Army you control.)

At the beginning of your upkeep, return up to one target creature card from your graveyard to the battlefield. If that creature is a Cleric, you gain life equal to that creature's mana value. Otherwise, each player loses that much life.

You may play lands from your graveyard.
{B}{G}, Sacrifice three lands: Return Endrison Nourisher from your graveyard to your hand.

Trample
{1}{G}{W}, Discard Enduring Force: Search your library for up to two basic land cards, reveal them, put them into your hand, then shuffle.
{G}{W}: Return Enduring Force from your graveyard to your hand. Activate only as a sorcery.

{U}: If Engrossed Reader doesn't have flying, put a flying counter on it.
{1}{U}: If Engrossed Reader has flying, draw a card, then discard a card. If you discarded a nonland card, put a +1/+1 counter on Engrossed Reader.
{1}{U}{U}: If Engrossed Reader has a +1/+1 counter on it, it becomes a copy of another target creature until end of turn.

Choose a card name, then look at the top card of your library. If it has the chosen name, you may exile it and you may play it from exile until end of turn.
Whenever a creature you control becomes tapped, you may return Enigma of Seventy Scrolls from your graveyard to your hand.

Recruit. (Create a 0/0 white Soldier Army creature token, then put a +1/+1 counter on each Army you control.)

This spell costs {2} more to cast for each target beyond the first.
Choose one or more —
• Target non-Gorgon creature gets -2/-2 until end of turn. Remove all counters from it.
• Return target creature or planeswalker card from your graveyard to your hand. You gain 4 life.
• Exile target player's graveyard.

Double strike
Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)

Whenever a land you control enters, add one mana of any color.
Whenever Enraged Fangwurm attacks, you may sacrifice a land. If you do, Enraged Fangwurm deals 2 damage to target player or planeswalker.
