The most effective approach follows the traditional color pie that defines both identity and gameplay mechanics: White - The color of order and protection that focuses on efficient creatures, removal spells, and defensive strategies Blue - The color of knowledge and control that emphasizes card draw, counterspells, and manipulating the game state Black - The color of power and ambition that utilizes life as a resource, creature removal, and graveyard interactions Red - The color of freedom and emotion that delivers fast aggression, direct damage, and chaotic effects Green - The color of nature and growth that ramps mana, plays large creatures, and destroys artifacts and enchantments Colorless/Multicolor - Cards that either require no specific mana or combine multiple colors for hybrid strategies and flexible deck-building options This sets up a very simple organization system: color

Artifact Color tag templates(None) Grothama, All-Devouring Other creatures have "Whenever this creature attacks, you may have it fight Grothama, All-Devouring." When Grothama leaves the battlefield, each player draws cards equal to the amount of damage dealt to Grothama this turn by sources they controlled
When your Pokmon V-UNION is Knocked Out, your opponent takes 3 Prize cards
1 The Fallen The Fallen is such a simple yet terrifying card
As far as the amount of play you'll get from a sleeve, Dragon Shields are unmatched
The effect here with the discard is weaker, but the alternative cost of paying two mana and 3 life for this is far better
