The Aetherdrift set has dropped a really interesting new ramp piece in the form of The Aetherspark, an equipment artifact planeswalker that seems like it would be a huge enabler. As a baseline, it cannot be attacked as long as it's attached to a creature and provides that creature a new ability wherein any damage that creature inflicts adds that many loyalty counters to the Aetherspark. This can be a huge gain even after only one swing with Atraxa. But then we get into it's 3 abilities.

+1, We attach the Aetherspark to a target creature we control and give that creature a +1 counter. A proliferatable +1 counter. Obviously we like putting +1's on our flying lifelinking commander and there's a side benefit to be had in using this ability to spread more of these counters onto any of our creatures and tokens.

-5, draw two cards. Hardly a price at all if it's attached to Atraxa. After only a single swing, she adds enough loyalty to make this a neutral ability.

-10, Add 10 mana of any one color. This I believe is one of the biggest draws as a single use of this ultimate can massively shift the power dynamics of the board and it's not all together difficult to reach with only a single turn cycle even when Doubling Season isn't in play.

Imagine this as a turn five play after summoning Atraxa turn four. Use the +1 ability to attach it to Atraxa. Loyalty goes to 5 and Atraxa gains a +1 counter. She swings in for 5 damage and adds 5 loyalty to the Aetherspark which now sits at 10. On the end step, proliferate the +1 and the loyalty counters leaving Atraxa at 6 power and the Aetherspark at 11 loyalty. That's enough to pop the -10 ultimate on the very next turn and survive with 1 loyalty, providing a shot of 10 mana on turn six to start really playing out your hand.

Obviously not immune to artifact destruction but "Dies to removal" applies to most everything else and without it, Atraxa or whatever other creature it's attached to needs to be dealt with in order to be targeted with an attack making it decently harder to get rid of. I expect this equipment planeswalker to pull a great deal of weight and will be swapping out my Thaumatic Compass  ^Flip for it.

While editing a deck to add the movie poster secret lair of Nature's Lore I saw it had a foil option in the Treatment dropdown menu even though I'm certain a foil version was never released for this particular secret lair.
