Draw two cards, then discard two cards. Flashback {2}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

When Muxus enters, reveal the top six cards of your library. Put all Goblin creature cards with mana value 5 or less from among them onto the battlefield and the rest on the bottom of your library in a random order. Whenever Muxus attacks, it gets +1/+1 until end of turn for each other Goblin you control.

This land enters tapped unless you control a Mountain. {T}: Add {R}. {R}, {T}, Exert this land: Add {R}{R}. If that mana is spent on a creature spell, it gains haste until end of turn. (An exerted permanent won't untap during your next untap step.)

As this land enters, you may reveal a Goblin card from your hand. If you don't, this land enters tapped. {T}: Add {B} or {R}.

If you control two or more other lands, this land enters tapped. {T}: Add {R}. {3}{R}: Until end of turn, this land becomes a 3/2 red Goblin creature with "Whenever this creature attacks, create a 1/1 red Goblin creature token that's tapped and attacking." It's still a land.

When this Equipment enters, it deals 3 damage to up to one target creature. Whenever one or more creatures die, put a rev counter on this Equipment. Equipped creature gets +X/+0, where X is the number of rev counters on this Equipment. Equip {3}

At the beginning of your upkeep, you may put a charge counter on this artifact. {T}: You may put a creature card with mana value equal to the number of charge counters on this artifact from your hand onto the battlefield.

Destroy target artifact. If you controlled that artifact, create three 1/1 red Phyrexian Goblin creature tokens.

As an additional cost to cast this spell, sacrifice a Goblin. Goblin Grenade deals 5 damage to any target.

At the beginning of your upkeep, create a colorless artifact token named Land Mine with "{R}, Sacrifice this token: This token deals 2 damage to target attacking creature without flying." Then flip a coin. If you lose the flip, this creature deals 2 damage to itself.

Other Goblins you control get +1/+1. Sacrifice a Goblin: Destroy target artifact.

Search your library for a card, put that card into your hand, then shuffle.
