Equipment cards with this ability enter the battlefield with a creature to wield them
Debuting in March of the Machine, incubate introduced a new type of artifact token to the game except instead of life or mana, these made Phyrexian creatures to bring terror to your enemies
(It's an artifact with " , , Sacrifice this token: You gain 3 life.") Ball Lightning Rarity: Rare TYPE: Creature SUBTYPE: Elemental CMC: 3 Mana cost: USD: $0.23 EUR: 0.35 TIX: 0.02 EDHREC RANK: 8904 (6/1) Trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.)

Whats to say that this new deck is theoretically better or more effective at doing something unique
Its also a perfect candidate for inclusion in Grixis Control lists with lots of spells that cost 3-mana or less
