Now that we have an understanding of mono color decks, let's take a Quick Look at the best way to build multi color decks. These can sometimes be a little more costly considering certain multicolor cards are not restricted to single color decks, which in turn can raise their popularity and demand.
However, it's not the cost that's a challenge; it's finding the perfect cards for your deck. The deck I'll be sharing in this article, for example, is one I still find myself "improving" despite how well it synergizes.
Infinite Guideline Station (IGS) was introduced to MTG in the August 2025 Edge of Eternities set. This is my favorite deck to play, not because of how strong it is but because of its sci-fi theme (nerd alert).
As we look at this commander, we find that IGS has a few important attributes.
- It is WUBRG (Five colors).
- Artifact
- Creature after charging 12 power.
- Concerned about multi-colored permanents.
- Creates robot tokens.
- Draws Cards
This gives us a wide variety of strategies we could use when building this deck. But we first want to pull out 35-40 land cards to act as our baseline. For a five-color deck, it might be best to start with eight basic lands of each color (If you are using a 2-4 color Commander, split your mana base accordingly). As you continue to build your deck, you can refine this or swap it out for other non-basic lands. Right now, our only concern is a basic build.
For a deck like this, you will want some cards that can assist with the multi-color IGS cares about. Below are a few options.

Command Tower: Is a common staple in all multi-color decks and will open you up to more than just a 1 Island/Plains/Mountain etc. mana.
Chromatic Lantern: Will open all your lands up to pay any color cost.
Leyline of the Guildpact: Acts similarly to Chromatic Lantern, however, also turning EVERY permanent you have on the field into multi-color. In a deck like this, it's your prized jewel. IGS will see every card in play as multi-color and you will draw cards equal with each attack.
Guildpact is not just helpful for an IGS deck, you can use it as a pseudo "Chromatic Lantern", or run both Lantern and Guildpact for extra mana security.
Once have your mana base figured out, adding creatures becomes the fun part. There are several different strategies you can employ. We don't have time to cover all the different types in detail, but here is a short list of deck strategies you may want to consider.
Token Generator: A deck like this could potentially be a huge problem. Action A triggers Action B creating additonal tokens. You might find yourself commanding a swarm of multi-colored tokens
Artifacts: This was my deck focus, while I do find it enjoyable, it comes with a risk. If someone decides to cast a Farewell and exile all artifacts, my creatures are toast!
Draw Triggers: Cards such as Scrawling Crawler, or Queza, Augur of Agonies will cause players to lose life for every card they draw.
Now there isn't too much else we can share without steering you into a particular direction of a deck build. This is your deck, you are in charge of how you build it. However, this at least gives you a basic outline of what you could potentially build, as well as what to look for in your commander.
As an honorary mention, if you do build an IGS deck. You may want to add Unwinding Clock, Loading Zone, or some other cards that can help proliferate your counters which in turn will allow you to get your IGS out quicker.
