你不會因步驟與階段結束失去未用盡的紅色魔法力。
當地脈暴君死去時，你可以支付任意數量的。當你如此作時，它對任意一個目標造成等量的傷害。

Rulings:

• 9/25/2020 You can keep red mana in your mana pool indefinitely while Leyline Tyrant is on the battlefield. That means if you add a red mana to your mana pool during one step or phase, you can spend it during a later step or phase, or even a later turn. Other types of mana will continue to empty from your mana pool as each step and phase ends.
• 9/25/2020 If a red mana you add to your mana pool has certain restrictions or riders associated with it (for example, if it was produced by Base Camp), they’ll apply to that mana no matter when you spend it.
• 9/25/2020 Once Leyline Tyrant leaves the battlefield, you have until the end of the current step or phase to spend whatever red mana is in your mana pool before it empties as normal. There is no penalty associated with this other than the loss of the mana.
• 9/25/2020 Leyline Tyrant’s last ability goes on the stack without a target. While that ability is resolving, you may pay any amount of red mana, including from the unspent mana you have. If you do, a second ability triggers and you pick one target to be dealt that much damage. This is different from abilities that say “If you do . . .” in that players may cast spells and activate abilities after mana is paid but before the damage is dealt.
