Any restrictions on the unspent mana aren't copied. For example, if you have {C}{W}{W}{B} with no restrictions on it and {U}{U}{U} that can be used only to cast artifact spells, you'll end up with {C}{C}{W}{W}{W}{W}{B}{B}, {U}{U}{U} that can be used only to cast artifact spells, and {U}{U}{U} that can be used for anything.

Price History
To study a single card is to glimpse the heart of a spell - a frozen moment of ambition, artistry, and arcane intent. Within each glyph lies a spark: a story untold, a duel turned, a destiny altered. Treat it not as mere parchment, dear seeker, but as a shard of the Multiverse itself.
