Whenever a creature you control phases in, draw a card.

Target creature gets -4/-0 until end of turn.
Crystallize. (Put a +1/+1 counter on a creature you control or create a Treasure.)

Target opponent reveals their hand. You choose a creature or sorcery card from it and exile that card.

{3}{B}: Each creature you control with menace gains lifelink until end of turn.

Return up to two target creature cards from your graveyard to your hand.
Coalesce {7}{B} (You may cast this from your graveyard for its coalesce cost. If you do, put it onto the battlefield as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

When Debaser of Truth enters the battlefield, if you control three or more Horrors, each opponent discards two cards.
Other Horror creatures you control get +1/+1.

If an opponent controls more lands than you, search your library for a Plains card. If an opponent controls more creatures than you, search your library for a creature card with mana value 2 or less. Reveal those cards, put them into your hand, then shuffle.

Target opponent discards a card. If a creature card was discarded this way, that player loses 3 life. If a land card was discarded this way, add {B}{B}. If a noncreature, nonland card was discarded this way, draw a card.

Haste

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 player activates an ability of an artifact, creature, or land, if it isn't a mana ability, Dedicated Weaponsmith deals 2 damage to that player.

Draw a card. Investigate. (Create a colorless Clue artifact token with “{2}, Sacrifice this artifact: Draw a card.”)

{B}{G}, {T}: Reveal the bottom card of your library and exile it. Target creature gets +X/-X until end of turn, where X is that card's mana value.
