Inverted Iceberg // Iceberg Titan

Craft is a payoff structure disguised as a cantrip. The front half asks nothing of the deck around it: drop it, mill one, draw one, and you have replaced the card while nudging the graveyard a card deeper. That nudge is the point later, because the transform side wants fuel, and the exile cost can come off the battlefield or straight out of the yard. So the artifact you bin early becomes the very thing you eat to flip this into a body. Any single milled card is a gamble, but the enters trigger is stocking the pantry regardless of what falls off the top.

The Golem you craft into reshapes combat on every swing. Its attack trigger taps or untaps a target artifact or creature: tap down a blocker before combat math resolves, or untap one of your own artifacts to fire a second activation off it. Because the trigger keys off declaring the attack rather than connecting, it works into an open board or against a wall you have no intention of trading with, and it does not care whether the creature is ever blocked. Each attack becomes a small tempo decision rather than a plain beatdown. The whole build wants you holding a spare artifact and a stocked graveyard, then hands back a body that pries the combat step open turn after turn.
