Cloak and PhaserHow it works & interactions with other cards

Understanding Strange New Worlds

The primary mechanic of Cloak and Phaser is its cost reduction ability, 'Strange new worlds.' This ability checks the names of all lands you currently control on the battlefield as you begin the process of casting the spell. For each land with a unique name, the total cost of the spell is reduced by {1}. This means if you control a Basic Island, a Basic Mountain, and a specialized non-basic land, the spell's cost is reduced by {3}. Note that having multiple lands with the same name, like two Islands, only counts as one differently named land for this calculation.

Step-by-Step Resolution

When Cloak and Phaser resolves, you follow the instructions in the order they are printed on the card. First, you create two 2/2 black Romulan creature tokens. These enter the battlefield simultaneously. Second, you draw two cards from your library. Finally, you must choose one card from your hand to discard. You cannot draw the cards and then wait to discard later; the entire sequence happens during the resolution of the spell.

Common Mistakes to Avoid

One common pitfall is misunderstanding how the cost reduction interacts with other effects. The mana value of Cloak and Phaser remains 9 regardless of how much mana you actually paid to cast it. Furthermore, you cannot reduce the cost below the single {U} requirement; the reduction only applies to the generic {8} portion of the cost. Ensure you have at least one blue mana source available regardless of how many differently named lands you control.

Strategy: When to Cast

This spell is most effective in 'Command Tower' or 'singleton' style formats where players naturally run many differently named lands. It is best used when you need to stabilize the board with blockers while looking for specific answers in your deck. Because it is a sorcery, you must plan your turn around it, but the discount allows you to potentially cast another spell in the same turn.

Interaction examples

Maximizing the Discount

Romulan

If you control a Command Tower, a Path of Ancestry, and a Sunken Hollow, you have three differently named lands. Cloak and Phaser now costs {5}{U} to cast. Upon resolution, you get two Romulan tokens to protect your life total while replacing the card in your hand.

High Mana Value Synergy

Aminatou's Augury

Because Cloak and Phaser has a mana value of 9, it is a prime target for Aminatou's Augury. If you exile Cloak and Phaser with the Augury, you can cast it for free as your sorcery choice, bypassing the land-name requirement entirely while still receiving the Romulan tokens and card draw.

Comparing Efficiency

Treasure Cruise

Much like Treasure Cruise uses the graveyard to reduce its cost, Cloak and Phaser uses your board state. If you control nine differently named lands, Cloak and Phaser costs only {U}, making it more mana-efficient for board presence than Treasure Cruise, though it draws one fewer card.
