Goldberserkerdragon Obligatory Grand Arbiter Augustin IV mention!

Stax is the most outrageous villian and azorius (Blue/White) loves stax.

Grand Arbiter Augustin IV or Lavinia, Azorius Renegade with effects like Mana Vortex, Winter Orb, Rest in Peace, Peacekeeper, Meekstone, and Armageddon will keep everyone begging for resources.

Or you could play Urza, Lord High Artificer and be the only one not affected by Static Orb.

Bread_my_Butter on GAAIV and Overrule cost reduction?

Yes, this is how the interaction works. This is becasue of how casting a spell is order : you choose a value for {X} before you have to pay for the cost(s). [Eg. You cast the spell choosing the value of {X} to be 7. You then apply any reductions to cost - {2} from Grand Arbiter Augustin IV - and then pay the costs of the spell.

If you want something to bring back to your table, here are the steps to casting a spell I found somewhere on reddit:

1. Move it to the stack

2. Choose modes, declare splices, and declare any additional/alternative costs (if applicable). Declare the value of X (if applicable). Declare what specific form of hybrid and phyrexian mana you will be paying (e.g. 2 life, U for a U/W cost)

3. Choose targets (if applicable)

4. Announce how an effect will be divided (if applicable)

5. Check if everything looks good so far or did you take an illegal action (if so, roll back to before step 1)

6. Take the base or alternative cost. Add any additional costs (whether chosen or imposed). Subtract any cost reducers. Finally, apply any effects (Trinisphere) that affect the total cost. Cost is now locked in (important if you sacrifice a cost reducer as part of paying the cost)

7. Activate mana abilities

8. Pay the cost

9. Any effects that modify the characteristics of the spell apply

10. Spell is now cast. Any relevant triggered abilities strigger.

Grand Arbiter Augustin IV reduces cost of blue and white spells by one each (for a max of - 2)

If i am casting Overrule with x=5 (from my mana sources) can i make my opponent basically pay 7 (7-2 reduced =5)?

For a fun one, Jegantha, the Wellspring and Progenitus.

Or how about going with Sliver-geddon and running The First Sliver and Sliver Overlord.

Or, because Urza, Lord High Artificer really needs access to all five colors, run him with Urtet, Remnant of Memnarch

Or perhaps you're just an evil person and you run Sakashima the Impostor so you can get a second Grand Arbiter Augustin IV on the battlefield.

Another pairing for those who hate their friends would be Maralen of the Mornsong and Ob Nixilis, Unshackled.

Cards that make it hard or impossible to play the game. It makes for a frustrating game cards like Stasis Blood Moon and Static Orb are stax so is Contamination, all three of these cards (and there are many many more cards like these) all of these cards make the game hard or impossible to play... so if you add a card like Contamination and your opponents can't play because they are not playing in black. They will feel like they should do the same to you. And then they will also play cards like these. That is a "stax and tax war" amungst your friends.

Tax are cards that make it cost more to do things in the game. Cards Like Thalia, Guardian of Thraben and Trinisphere and Grand Arbiter Augustin IV are tax effects.

Maybe a copy or two of Grand Arbiter Augustin IV not only does he inversely ramp for you by decreasing your spell costs, he also simultaneously taxes all spells your opponent would play...
