Spire of Industry

When Worf enters, create a 2/1 red Klingon Warrior creature token with haste. Battlefront — Whenever you attack, exile the top X cards of your library, where X is the number of opponents you attacked this turn. Until the end of your next turn, you may play those cards.

Yes — 1, T: Untap two other target creatures. No — 2, T: Tap two other target creatures.

Battlefront — Whenever you attack, for each opponent you attacked this turn, create a tapped and attacking 2/1 red Klingon Warrior creature token with haste.

Other Officers, Artificers, Doctors, Pilots, Scientists, and Spacecraft creatures you control get +2/+2.

Whenever a non-Human creature enters, you may pay 1. If you do, draw a card.

Whenever an opponent draws a card during your turn, create a 1/1 blue Faerie creature token with flying.

Seek out — Whenever you draw your second card each turn, discover 4. (Exile cards from the top of your library until you exile a nonland card with mana value 4 or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)

All nonartifact creatures get -X/-X until end of turn, where X is the number of artifact creatures you control.
