结界
于异种接殖进战场时,选择一种生物类别。
每个由你操控的生物均额外具有该类别。
You must choose an existing _Magic_ creature type.
Creature cards not on the battlefield and creature spells are not affected.
Replacement effects that modify creatures of a certain type as they enter the battlefield will apply (or not apply) after you apply this effect. For example, if Warrior is the chosen creature type and you control Bramblewood Paragon, a Runeclaw Bear would enter the battlefield with an additional +1/+1 counter.
