Skulls & Broccolis Green has access to an engine that generates a huge advantage with a boost to mana production and fixing as well as a steady stream of cards and life and threats
Of course, we're placing a lot of emphasis on "most of the time" here
For one-off edge cases, its usually faster to use a generic token, a dry-erase token, or a spare card in a sleeve
But, when it came to this deck and others in the Warhammer 40,000 product release, Necron Dynasties had so much flavor behind it
And the cards that may be similar are much older cards, which is cool
The ratios for this deck is very good: lots of amazing mana advantage cards that really take advantage of the archetype like Sanctum Weaver, tons of Enchantress for card draw like Mesa Enchantress, great one-sided board wipes like Doomwake Giant etc
