When this creature enters, investigate. (Create a Clue token. It's an artifact with "{2}, Sacrifice this token: Draw a card.")

When you attack with three or more creatures, conjure a card named Mox Ruby into your hand. This ability triggers only once. {1}{R}: Creatures you control get +1/+0 until end of turn.

As long as this creature has three or more counters on it, it has flying and vigilance. Tap three untapped artifacts and/or creatures you control: Put a +1/+1 counter on this creature. Scry 1. Activate only as a sorcery.

Flying At the beginning of combat on your turn, target creature you control perpetually gets +1/+0. Then choose a creature card in your hand. It perpetually gets +1/+0.

Menace At the beginning of your upkeep, you may create a Treasure token. When you do, target opponent creates a tapped Treasure token. Whenever this creature attacks, it deals damage to defending player equal to the number of artifacts they control.

First strike When Impetuous Lootmonger enters, discard a card, then heist target opponent's library. Whenever you cast a spell you don't own, create a tapped Treasure token.

When Jewel Mine Overseer enters, conjure seven cards named Seven Dwarves on top of your library. They perpetually gain "When this creature enters, draw a card." Then shuffle. At the beginning of your upkeep, exile the top card of your library. You may play that card this turn.

Indestructible, haste At the beginning of combat on your turn, put a +1/+1 counter on Tajic, Legion's Valor. Then conjure a card with mana value equal to the number of +1/+1 counters on it from Tajic, Legion's Valor's spellbook onto the battlefield. It gains haste until end of turn and attacks this combat if able.

When this enchantment enters, exile all graveyards. If a card or token would be put into a graveyard from anywhere, exile it instead.
