How does "spend this mana only" clauses interact with Mana Reflection, Heartbeat of Spring, Doubling Cube, Horizon Stone, Green Omnath?
Asked by curmevexas 2 years ago
Suppose I pay 2GG and tap Castle Garenbrig for six G. It specifies that I can "spend this mana only to cast creature spells or activate abilities of creatures." How does this clause interact with Mana Reflection , Heartbeat of Spring , Doubling Cube , Horizon Stone , Omnath, Locus of Mana ? What mana is still restricted by that clause vs what can be used for other mana costs? Any other weird card interactions with that clause?

For Heartbeat of Spring , is it just the one extra G mana that is unrestricted (or is it everything)?

curmevexas sorry for being unclear! The mana that you as the player add (the extra ) is the mana that you may spend on anything.

Using the cards you mentioned as examples:
Mana Reflection will not allow for the additional mana to be used on anything but creature spells/abilities, because the mana produced is still being produced by Garenbrig itself.
Heartbeat of Spring , however, allows you as the player to add the mana, meaning it isn't tied to the Castle. You may spend that mana on anything.
Doubling Cube , similarly to the Heartbeat, adds the mana independently of Castle Garenbrig--you may spend that additional mana on anything (this card was, incidentally, the basis for a legacy deck that utilized Jeweled Lotus ).
Horizon Stone simply retains the mana, it doesn't change its properties. Therefore, that mana may only be spent on creature spells/abilities. The same is true for Omnath.
