Seven of Nine, UnassimilatedHow it works & interactions with other cards

Efficiency and Land Diversity

The first ability triggers at the start of your precombat main phase. You will always draw a card first. However, to keep that card without discarding, you must control five or more lands with different names. Note that basic lands with the same name (like two copies of Island) only count as one name. You need five unique names, such as Island, Forest, Command Tower, Exotic Orchard, and Reliquary Tower.

The Transformation Step-by-Step

Activating the second ability requires a significant mana investment and a strict condition: you must control seven or more differently named lands. Once activated, Seven of Nine's base power and toughness become 7/9. This is a layer 7b effect. Any other effects that modify power and toughness, such as +1/+1 counters or equipment, are applied after this base change is established.

Strategic Timing

Because the card draw happens at the beginning of your first main phase, Seven of Nine must be on the battlefield before that phase begins to trigger. If you cast it during your first main phase, you will have to wait until your next turn to get the draw. The transformation ability can be activated at any time you have priority, provided you meet the land requirement, making it a potent defensive tool or a surprise attacker.

Interaction examples

Reducing the Cost of Entry

Foundry Inspector

With Foundry Inspector on the battlefield, the cost to cast Seven of Nine, Unassimilated is reduced by {1}, allowing you to deploy it for just {U}. This allows you to start meeting the trigger requirements earlier in the game.

Fixing for High-Cost Activation

Ornithopter of Paradise

To activate the 7/9 transformation, you need {6}{U}. Ornithopter of Paradise can tap for blue mana or any other color you might be missing, helping you reach the high mana requirement while you focus on playing uniquely named lands to satisfy the activation condition.

Maintaining Card Advantage

If you control an Island, a Mountain, a Swamp, a Forest, and an Evolving Wilds at the start of your first main phase, the ability triggers. You draw a card and, because you control five differently named lands, you do not have to discard a card.
