Changes

Each Planeswalker has an affinity to a one [[color]], in some cases or two or even three colors, or every color (e.g. A Planeswalker's [[deckKarn, Scion of Urza]] may generally contain only [[). Every Planeswalker can use any colorless card]]s including an affinity color, or colorless but any colored Planeswalker must use colored cardsmatching one of their affinities. The upper limits on the number of Creature, Spell, and [[Support]] cards in the deck are also specific to each Planeswalker-specific.

[[Origins]], [[Battle for Zendikar]], and [[Oath of the Gatewatch]] Planeswalkers all have lower mana bonuses than this, as do many others before the [[Ixalan]] set. PWs that break the Mana bonus rule may, rarely, be released; is the sole example as of August 2024. Unusual mana gain is part of the design of colorless walkers, and there is no easy rule to define their bonuses. There are clear benefits to playing Planeswalkers with high spike bonuses with mana conversion, and when playing without mana conversion, to use Planeswalkers with a balanced spread of bonuses. Some Planeswalkers have abilities that benefit their mana bonuses; notably [[Karn, Scion of Urza]], [[Sarkhan Unbroken]], [[Tamiyo, Field Researcher]] , and [[Ugin, the Spirit Dragon]].
