Kaldra Compleat is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Living weapon Indestructible Equipped creature gets +5/+5 and has first strike, trample, indestructible, haste, and "Whenever this creature deals combat damage to a creature, exile that creature." Equip

Complete guide

Kaldra Compleat is the ultimate culmination of Mirrodin's legendary artifacts, now perfected by the Phyrexians. This monstrous equipment instantly transforms even the smallest token into a massive, indestructible threat. Whether it is entering the battlefield for the first time or being re-equipped, it provides an overwhelming suite of offensive and defensive abilities.

What It Does

Kaldra Compleat is a legendary equipment featuring the Living weapon keyword, which means it enters the battlefield with its own pilot. It grants the equipped creature +5/+5, first strike, trample, haste, and indestructible. Furthermore, it adds a powerful triggered ability: whenever the creature deals combat damage to another creature, that damaged creature is exiled immediately.

How It Resolves Step by Step

When you cast Kaldra Compleat and it enters the battlefield, the Living weapon ability triggers. First, you create a 0/0 black Phyrexian Germ creature token. Then, you attach Kaldra Compleat to that token. Because the equipment grants +5/+5 and indestructible, the Germ becomes a 5/5 creature and survives. Because it has haste, the token can attack or tap for abilities the very turn the equipment enters the battlefield.

Common Mistakes

A frequent oversight is forgetting that Kaldra Compleat itself is indestructible, even if it is not attached to a creature. However, its exile ability only triggers on combat damage; non-combat damage (like a spell effect) won't cause the exile trigger. Also, keep in mind that if the creature is removed in response to the Living weapon trigger, the equipment stays on the battlefield but the Germ will die immediately due to having 0 toughness.

When to Play It

This card is best used to break stalemates or pressure opponents who rely on large blockers. Since it grants trample and first strike, it can kill most blockers before they can deal damage back, and anything that survives the initial hit is exiled anyway. It is an excellent target for cards that allow you to cheat artifacts into play, bypassing its high mana cost.

Interaction examples

Creating a Living Weapon

Phyrexian Germ

When Kaldra Compleat enters the battlefield, you create a Phyrexian Germ token. You immediately attach the equipment to it, turning the 0/0 token into a 5/5 indestructible creature with haste and several other keywords.

Dealing with Destructive Entrants

Meteor Golem

If your opponent plays Meteor Golem and targets Kaldra Compleat with its destruction ability, nothing happens. Because Kaldra Compleat has the keyword 'Indestructible' printed on it, the Golem's 'destroy' effect fails to send the artifact to the graveyard.

Anti-Counter Protection

Chimil, the Inner Sun

With Chimil, the Inner Sun on the battlefield, your Kaldra Compleat cannot be countered by spells or abilities. This ensures that your 7-mana investment successfully enters the battlefield to create its Phyrexian Germ token.
