Further expanding on the above answer, means "generic mana" and can be paid with any color including colorless while must be paid with colorless.

The gatherer ruling you were looking at was input before created by Wastes was put into the game. While the ruling does say it cannot reduce the colored portion of a mana cost, due to the formatting, it is implied that the cost reduction only applies to "generic mana" and not colorless mana.

Basically, Heartstone only reduces the amount of "generic mana" that must be paid to activate activated abilities. Any attribute specific costs cannot be reduced.

No- the oracle text on Heartstone is "Activated abilities of creatures cost less to activate. This effect can't reduce the amount of mana an ability costs to activate to less than one mana.

it isnt Activated abilities of creatures cost less to activate. This effect can't reduce the amount of mana an ability costs to activate to less than one mana.

Because Eldrazi Displacer requires colorless mana in the activation cost of its ability, can Heartstone reduce the portion of its cost requiring ? In other words would i be able to activate its ability with only 2 islands?

The gatherer says that heartstone cannot be used to reduce the colored portion of a mana cost, however this is distinctly a colorless cost.

A number of changes to report for the deck! I added a potential infinite combo involving three pieces. Deepfathom Skulker has been removed for Paradise Mantle. The mantle is used for Knacksaw Clique which has replaced Monastery Flock to continuously pay for its own ability. Heartstone is used to make the cost cheaper. Returned Centaur is removed in favor of Rhystic Study.

Fyi boros keyrune is illegal here. I wouldnt pkay with a keyrune regardless. If you're looking for in-color ramp try Solemn Simulacrum, and Talisman of Indulgence. As for the deck you may want to consider Heartstone, Blowfly Infestation, and Nest of Scarabs.

Mairsil, the Pretender

Quicksilver Elemental

Gilded Lotus

Prismatic Geoscope

Hateflayer

Just for reference

~~~

Please describe to me, among the 4/5 cards listed in the combo, which one is allowing you to:

"Untap for U Mana"

Besides Hateflayer, there is no other way to untap Mairsil with the listed cards in the combo. I am unsure where you are getting an extra untap ability from, but it is not with the listed cards.

As described, this combo WOULD work if you had a way to discount the mana you were using. Add in Heartstone or Training Grounds and this combo DOES work:

Tap for UUUUse U for Quicksilver ability - refresh abilitiesUse UU to untap with Hateflayer - Quicksilver allows U mana to be used in place of any other color (training grounds makes it so its U, letting you make infinite mana if you cannot target a player for example)Mairsil now has the ability to tap again for UUU and can repeat the steps for an insta-kill
