Where it struggles is with a lack of artifacts and enchantments, and 40 total lands that feel a little overkill, especially when you could find other ways to produce mana if needed
Thanks to X-drop creatures, even the one-mana requirement is a bit misleading
We also have some interesting aura/enchantment support cards like Winds of Rath which can be a one-sided board wipe for us
Legendary Creature - Demon Kozilek's Unsealing Devoid (This card has no color.) Whenever you cast a creature spell with mana value 4, 5, or 6, create two 0/1 colorless Eldrazi Spawn creature tokens with "Sacrifice this token: Add ." Whenever you cast a creature spell with mana value 7 or greater, draw three cards
It automatically moves your equipment onto your creatures the moment they show up during combat, helping you skip those expensive equip costs and stay aggressive
