Thaumatic Compass // Spires of Orazca

At the beginning of your upkeep, you may have two target players exchange life totals.

+2: Create a 2/2 black Pirate creature token with menace. −3: Destroy target artifact, creature, or enchantment. Create a Treasure token. (It's an artifact with "T, Sacrifice this token: Add one mana of any color.") −10: Target player's life total becomes 1.

1, T: Scry 1. Put a landmark counter on this artifact. Then if there are three or more landmark counters on it, remove those counters, transform this artifact, and create three Treasure tokens. (They're artifacts with "T, Sacrifice this token: Add one mana of any color.")

Whenever you cast a spell from your hand, reveal the top X cards of your library, where X is that spell's mana value. You may cast a spell with mana value X or less from among cards revealed this way without paying its mana cost. Put the rest on the bottom of your library in a random order.

Double strike Whenever this creature attacks, other creatures you control gain double strike until end of turn.

Other Dinosaurs you control have haste. When this creature enters, create a 3/3 green Dinosaur creature token with trample.

Gain control of target creature with mana value X.

At the beginning of your upkeep, exile the top card of your library. If it's a nonland card, you may cast that card this turn. Whenever you cast your third spell in a turn, you may transform Vance's Blasting Cannons.
