Gold MyrHow it works & interactions with other cards

A Mana Source on Legs

Gold Myr features a mana ability that allows you to tap it to add one white mana ({W}) to your mana pool. Unlike spells, mana abilities do not use the stack and cannot be responded to, though you must wait for the creature to lose summoning sickness before you can activate it.

How it Resolves

Step 1: Ensure Gold Myr has been under your control since the beginning of your most recent turn. Step 2: Announce you are activating the ability and tap the permanent as the cost. Step 3: Immediately add {W} to your mana pool; this happens instantly and does not allow players to cast spells in between the tap and the mana appearing.

Artifact Synergy and Vulnerability

Because Gold Myr is both an artifact and a creature, it is subject to more types of removal than a basic land. It can be destroyed by 'destroy target creature' effects as well as 'destroy target artifact' spells, so plan your mana base accordingly.

When to Play Gold Myr

This card is best utilized in the early turns (turn 2) to accelerate into 4-mana spells by turn 3. It is particularly effective in decks that care about the number of artifacts you control or those that need extra white sources for strict mana requirements.

Interaction examples

Accelerating into Taxes

Esper Sentinel

On turn one, you play Esper Sentinel. On turn two, you play Gold Myr. On turn three, even if you miss a land drop, you can tap Gold Myr for white mana to help pay for a second spell or to keep mana open for your Sentinel's tax effects if an opponent casts a noncreature spell.

The Artifact Ramp Package

Ornithopter of Paradise

By running both Gold Myr and Ornithopter of Paradise, you increase your deck's density of artifact mana. If you have both on the battlefield, you can tap them together to produce {W} and one mana of any color, providing a total of two extra mana to cast larger spells ahead of schedule.
