mtg flicker cards Ghostly - Commander Masters - 0098 Put it onto the battlefield if its mana value is 2 or less Flickerwisp MTG - Double Masters

And this one is a grisly necklace of eyeballs and ears

Hraesvelgr of the First Brood Hraesvelgr of the First Brood is great combined with other big creatures

Smugglers Copter My pick for the most-played Vehicle of the set, Smugglers Copter is aggressively costed at only two mana and a Crew size of one

There are also a handful of good board wipes like Their Name Is Death and Organic Extinction that decks heavy on artifact creatures can use to devastate the opponents and keep their board state up

The cards above may be generally good, but theres always another card thats just perfect for your specific deck

Ive been careful to highlight the potential of temporary recursion, but when the effects are both reusable, the opportunity to build up a lasting board through this card alone is hard to ignore
