mtg tiefling cards Zevlor, Elturel Exile | Promotional there is an additional combat phase Subtype: Tiefling, 16 cards |

The versatility of it holds the value of it reasonably high but at the end of the day you are always paying two mana for a one mana effect

Five cards take on most of this value: Birds of Paradise at $11 , The Gaffer at $9.23, Toxic Deluge at $8.59, Treebeard, Gracious Host at $5.20, and Sanguine Bond at $6

I could easily see it as the breakout card of the set

If you would put one or more counters on a permanent or player, put twice that many of each of those kinds of counters on that permanent or player instead

When attached to the right creature, theres no question that The Aetherspark is a great high-value card
