#generic mana

[magicjudge]

Does Inspiring Statuary allow Improvise to pay for Colorless mana, or just Generic mana? I.E. Thought-Knot Seer.

Improvise can only pay generic costs, i.e. those indicated by numbers in circles. It can’t pay colored or colorless costs.

Regarding Kruphix, God of Horizons, mana becomes colorless with his last ability. Does that mean colorless as in the wastes symbol mana or colorless as in generic mana? Since it was printed before Oath of the Gatewatch and I can't find clarification.

Generic mana isn’t a type of mana. A generic mana symbol is a number in the mana circle that represents a cost payable with any type of mana. Generic mana can’t be added to your mana pool.

All colorless mana that’s added to your mana pool is the same, i.e. the kind now represented by the diamond symbol and in text as C.

Does Blasted Landscape add the Diamond symbol colorless mana or the generic mana?

Generic mana can’t be added to your mana pool. Generic mana is a cost. Previously, the same set of mana symbols were used to represent colorless mana being added to your mana pool and generic mana in the costs of spells or abilities. This changed with Oath of the Gatewatch. The diamond symbol, shorthanded as {C}, represents colorless mana being added to the mana pool, and specific colorless costs in rare cases. All cards that were printed saying they added {1} or {2} or {3}, etc. to your mana pool now add{C} or {C}{C} or {C}{C}{C}, etc. to your mana pool as appropriate.

Regarding cost reducers & (C) mana. Given costs can be reduced by specific mana (Edgewalker), & that 'colourless' & ' generic used to be both represented by (1), cards like Herald of Kozilek could be misinterpreted. Is there a ruling to cover this?

There’s the fact that Herald of Kozilek’s oracle text says it reduces by 1 generic mana, and that there are NO cards that reduce costs by C.

Can i use adakar wastes' first tap ability as colorless for the new color/ set? Or does it count as generic mana?

Generic mana can’t be added to your mana pool. Generic Mana can only appear in costs and cost reductions. Anything that adds mana represented by a number in a circle to your mana pool adds that much colorless mana to your mana pool.

Hi, I encountered someone on a MtG forum today who stated that reducing the cost of a spell by <>(colorless) could reduce it's cost by <> or 1. Then they said their claim was backed up by rule 117.7b. This doesn't seem correct. Can you weigh in?

That’s correct.

If an effect would reduce the cost of a spell by a specific mana symbol (vs. reducing it by an amount of generic mana), then the cost will be reduced by that much generic mana if there are no symbols of that type in the cost.

Note that some cost reduction effects specifically prohibit this reduction rollover, such as Edgewalker and Ragemonger.

[magicjudge]

In the instance of Edgewalker, there is a specific type of mana included in the cost reduction. Since the previous version of printing {C} on cards that produce colorless was just 1, could it be interpreted that errata on Herald of Kozilek is “Colorless spells you cast cost {C} less to cast”?

No, it couldn’t. There are no cards that reduce a spell’s cost by C. No cards are being changed to reduce costs by C.

Herald of Kozilek, Animar, Mizzix and other cost reduction effects still reduce costs only by generic mana.

I have a kozilek edh and I was wondering a lot of lands say tap add 1 to mana pool is it generic or colorless?

Generic mana is only ever a cost and represents a cost that can be paid with colorless mana or mana of any color. Cards that previously added mana represented by generic mana symbols now adds that much colorless mana to your mana pool.
