Morphling 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

: Untap this creature. : This creature gains flying until end of turn. : This creature gains shroud until end of turn. (It can't be the target of spells or abilities.) : This creature gets +1/-1 until end of turn. : This creature gets -1/+1 until end of turn.

Complete guide

Morphling is one of the most versatile creatures in Magic's history, often referred to as the 'Swiss Army Knife' of blue creatures. Its five activated abilities allow it to adapt to almost any combat situation or spell interaction on the fly.

A Master of Adaptation

Morphling features five distinct activated abilities that can be used as many times as you can pay the cost. It can untap itself for one blue mana, grant itself flying or shroud, and shift its power and toughness stats to favor either offensive pressure or defensive stability.

Activating the Abilities

When you activate Morphling's abilities, they go on the stack like any other activated ability. For the stat-shifting abilities, remember that they last until the end of the turn and are applied in the order they resolve. You can activate the shroud ability in response to an opponent's spell to make Morphling an illegal target.

Navigating Stat Changes

A common mistake is forgetting that Morphling's toughness cannot drop below 1 without it being destroyed. If you activate the +1/-1 ability too many times, Morphling will die when its toughness reaches 0. Always calculate your mana and the resulting toughness before committing to a chain of activations.

When to Use Morphling

Morphling is best used as a finisher in control decks. By holding back mana, you can protect it with shroud, block an attacker and untap it, or fly over your opponent's blockers for lethal damage once they are tapped out.

Interaction examples

Evasive Maneuvers

Solemn Simulacrum

If your opponent controls a Solemn Simulacrum, it may block Morphling on the ground. By paying one blue mana to activate Morphling's flying ability, you can fly over the Golem and deal damage directly to your opponent.

Protection from Targeted Removal

Suppose your opponent tries to destroy Morphling with a targeted spell. In response, you can pay one blue mana to activate its shroud ability. When the opponent's spell tries to resolve, it will find that Morphling is no longer a legal target and the spell will fail to resolve.

Maximizing Combat Damage

Roaming Throne

While Roaming Throne doubles triggered abilities of a chosen type (like Shapeshifter), it does not affect Morphling's activated abilities. However, you can still use Morphling's {1}: +1/-1 ability four times to turn it into a 7/1 attacker, then pay one blue mana to give it flying to ensure it hits your opponent for massive damage.
