天界柱廊

Text:

天界柱廊须横置进战场。
：加或到你的法术力池中。
：直到回合结束，天界柱廊成为4/4白蓝双色，具飞行与警戒异能的元素生物。 它仍然是地。

Rulings:

• 3/1/2010 A land that becomes a creature may be affected by “summoning sickness.” You can’t attack with it or use any of its <img src="/Handlers/Image.ashx?size=small&amp;name=tap&amp;type=symbol" alt="Tap" align="absbottom" /> abilities (including its mana abilities) unless it began your most recent turn on the battlefield under your control. Note that summoning sickness cares about when that permanent came under your control, not when it became a creature.
• 3/1/2010 When a land becomes a creature, that doesn’t count as having a creature enter the battlefield. The permanent was already on the battlefield; it only changed its types. Abilities that trigger whenever a creature enters the battlefield won’t trigger.
• 12/7/2018 Once Celestial Colonnade has attacked, tapping it for mana won’t remove it from combat.
• 12/7/2018 If Celestial Colonnade can’t attack unless you pay a cost that includes a mana payment, you may attack with it and tap it to pay for that cost. It will still attack in this case.
