The main concept of this Magic: the Gathering deck is to utilize the key combo card Indomitable Creativity to create powerful and game-changing effects. By resolving Indomitable Creativity with target cards such as the Goblin Shaman token generated from the Fable of the Mirror-Breaker, the deck aims to generate a strong board presence, advantageous situations, and chaining card advantage.

Additionally, the deck incorporates a variety of spells in the Izzet colors like Make Disappear, Fiery Impulse, and Prismari Command to control the board and disrupt the opponent’s deck strategies. Having this core setup, it is the role of the player to see to it that the sideboard will align well with the metagame while also maintaining the core deck strategy.

The sideboard is an essential part of competitive Magic decks, allowing you to adjust your deck to better handle specific matchups. This is particularly important if you are using a Combo deck in the Pioneer format. We know a lot of variance of decks so we make sure that our sideboard plan would cater their possible sideboard cards against us.

First, Understand Your Deck’s Weaknesses – Identify the weaknesses of your main deck. What types of decks or strategies give you trouble? Sideboarding is an opportunity to shore up these weaknesses.

Next, Include Hate Cards. Your sideboard should include cards that are effective against common strategies in the format. For example, if aggressive creature decks are prevalent, you might want cards that can handle creatures efficiently. If graveyard-based strategies are prevalent, consider including cards that can exile or disrupt graveyard interactions. Against control decks, you might want cards that generate card advantage or can counter/control their spells more effectively.

SB plans usually include Artifact and Enchantment Removal. Cards that can deal with problematic artifacts or enchantments are valuable in the sideboard. This can be crucial against decks that rely on powerful artifacts or enchantments. In an Izzet deck setup, bouncing or countering them is your best option.

After lining up a potential pile of SB cards, Test your Sideboard. Playtesting is crucial for refining your sideboard plan. It helps you understand which cards are most effective in certain matchups and whether adjustments are needed.

Do also Maintain a Balanced Sideboard. Avoid overloading your sideboard with too many situational cards. Having a well-balanced sideboard allows you to adapt to a variety of matchups.

Last, always Stay Informed. The metagame can evolve, so regularly check for updates on the Pioneer metagame by checking on websites such as MTG Top 8 dot com. This will help you adjust your sideboard to be well-positioned against the decks you’re likely to face.

Remember, the effectiveness of a sideboard plan can depend on the specific metagame you’re playing in. If possible, consult with experienced players, check tournament results, and adapt your sideboard based on the shifting dynamics of the Pioneer format.
