Well I played the Elemental deck unaltered (I like to play a precon raw before upgrading) and... whoever doubted Ashling as any good were idiots. She is every bit a kill on sight commander as O.G. Khalia.
At one point I got her and the Mass of Mysteries out. Evoked this guy...

The copy then can return your original to hand. Then you give the copy mryiad, and get 2 more things out of the graveyard.
At a different point another player had added the twinflame to the deck and it landed on the battlefield...
Do you like paying 3 mana to evoke mull drifter and then drawing 12 cards? I can tell you one guy who really enjoyed that value. Oh right, he had Risen Reef out, so that was like an additional 6 cards he got to fondle.
At this point if WOTC is going to keep putting in copy effects into their precons then the things should just come with a dozen infinitokens.
