This week's question is inspired by DrJones' question originally posted in the Community Forum.

In last week's question, most Adepts agreed that Red and Blue are by far the strongest colors in the format. What kinds of cards could Wizards print that would reasonably strengthen the other three colors, while maintaining fidelity to the color pie and a relatively "fair" power level? Feel free to use real decks as illustrative examples. (For example, white would be significantly stronger if (Deck) had a card like (fill in the blank) to bolster its strategy against (existing metagame challenges). If possible, consider how your suggestions might impact other formats like Block Constructed and Standard and how that might affect its feasibility. Feel free to suggest as many hypothetical cards as you like. It is not necessary to specify an exact casting cost/power/toughness/card wording here. We're looking for general examples, although you can get more specific if it's relevant to your point.
