裁定
You “tap a permanent for ” only if you activate a mana ability of that permanent that includes the 
symbol in its cost, and only if it produces one or more as it resolves.
If you tap a permanent for more than one , you add only one additional .
An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
Forsaken Monument’s last ability won’t trigger when you play a land.
A land is normally colorless, regardless of what colors of mana that land can produce. If an effect makes a colorless land into a creature without specifying that it becomes a certain color, the land creature gets +2/+2.
