Trinisphere + Sphere of Resistance

[Rascal]

Hi guys,

I guess I should know this, but I´m not sure about it.

How this will works:

Trinisphere
Artifact
As long as Trinisphere is untapped, each spell that would cost less than three mana to cast costs three mana to cast.

Sphere of Resistance
Artifact
All spells cost an additional 1 to play.

or

Lodestone Golem
Artifact Creature
Nonartifact spells cost 1 more to cast.


So...

If I have Trini on the battlefield+Sphere of Resistance+Lodestone, how much will cost next spell....?

I want play some spell e.g. for three mana. Will I have to pay 2 more due to Lodestone and Sphere, or I fullfill condition of Trinisphere and so - done.

In other words - does this efects summed up?

How is it works?

THX in advance

Trinisphere:
As long as Trinisphere is untapped, each spell that would cost less than three mana to cast costs three mana to cast. (Additional mana in the cost may be paid with any color of mana or colorless mana.

Trinisphere only affects spells that cost less than 3 mana to cast. Any spell that costs less will be made to cost 3, regardless of how many Sphere of Resistances or Lodestone Golems you have in play.

However if you play a spell that cost 3 or more to begin with, than that spell will be affected by said Spheres and Golems.

In your example you stated that you wish to play a spell that costs 3. You will have to pay 5 for it due to your Sphere of Resistance and Lodestone Golem, there is no condition filled for Trinisphere.

Costs work like this with spheres:

Let's say you have a Sphere of Resistance, a Jet Medallion, a Trinisphere (untapped), and you are attempting to cast an Abyssal Gatekeeper.

The Sphere of Resistance makes you pay an additional mana. The Jet Medallion makes you pay one generic mana less. Then, and only then, the Trinisphere says, "Did you pay 3 mana for this spell?" If yes, it does nothing. If no, you pay additional mana until you've paid three.

In this situation, the Gatekeeper would cost a total of :2::b:.

Now let's say you have the Sphere and the Trinisphere, but no Medallion. In this situation, the gatekeeper would cost :2::b:, as well, as again the Trinisphere checks and applies last.

In a third example, let's say instead of the Gatekeeper, you're casting a Vampire Nighthawk. The Sphere adds a mana, and then the Trinisphere asks if you paid three mana. The answer is yes, so it doesn't effect the spell. The Nighthawk costs :2::b::b:.

The main thing to keep in mind is that Trinisphere is always applied last, and only does anything if the spell is still at less than 3 mana after all other modifiers are applied.

THX - very useful clarification.
