Noncreature spells cost more to cast.

Whenever a player casts a noncreature spell, put a collection counter on this enchantment. Then if there are three or more collection counters on it, sacrifice it. If you do, draw a card, then you may search your library for a Plains card, put it onto the battlefield tapped, then shuffle.

For each opponent, exile up to one target permanent that player controls with an even mana value. (Zero is even.)

Adamant — If at least three colorless mana was spent to cast this spell, return a permanent card with an odd mana value from your graveyard to the battlefield.

Destroy target creature, enchantment, or planeswalker. Its controller creates two Map tokens. (They're artifacts with ", , Sacrifice this token: Target creature you control explores. Activate only as a sorcery.")

Exile all creatures. For each card exiled this way, you may play that card for as long as it remains exiled, and mana of any type can be spent to cast that spell. Exile Heartless Conscription.

Threshold — As long as seven or more cards are in your graveyard, this enchantment has "Whenever an opponent casts a spell, you may put a creature card from your hand onto the battlefield."

You draw two cards and you lose 2 life. Each opponent gets a poison counter.

Read ahead (Choose a chapter and start with that many lore counters. Add one after your draw step. Skipped chapters don't trigger. Sacrifice after III.)

Return target permanent card from your graveyard to the battlefield with a hexproof counter and an indestructible counter on it.
