Dollhouse of Horrors

At the beginning of combat on your turn, draw a card. Then you may exile an artifact or creature card from your hand. If you do, create a token that's a copy of the exiled card, except it's a 3/3 Golem artifact creature in addition to its other types.

Prototype — 2/3 (You may cast this spell with different mana cost, color, and size. It keeps its abilities and types.)

, Sacrifice this creature: Create an X/X colorless Golem artifact creature token, where X is three times this creature's power. It gains haste until end of turn. Activate only as a sorcery.

, : An opponent chooses target creature they control. Create a token that's a copy of that creature. That token gains haste until end of turn. Exile the token at the beginning of the next end step. Activate only as a sorcery.

Fallen Warrior — As an additional cost to cast this spell, you may exile a creature card from your graveyard.

Trample

Plasma Incinerator — Whenever this creature attacks, if a card is exiled with it, it gets +X/+X until end of turn, where X is the power of the exiled card.

: This creature gets +2/+2 until end of turn. If you control creatures named Mine Worker and Tower Worker, put two +1/+1 counters on this creature instead. Activate only once each turn.

+1: Reveal the top two cards of your library. An opponent chooses one of them. Put that card into your hand and exile the other with a silver counter on it.

−1: Put a card you own with a silver counter on it from exile into your hand.

−2: Create a 0/0 colorless Construct artifact creature token with "This token gets +1/+1 for each artifact you control."
