This is a very diverse card , your minion can benefit from it by swapping so that it may attack directly with big Atk or you can trick your opponent's minion by swapping his stats.

Poor Doomsayer won't be saying any doom when you have this card in your hand! 

I.. knew it...

True this is very anti doomsayer card.

Much better card than Inner Fire

[insert “Up with the sickness joke” here]

This isn't a backup Inner Fire. Inner Fire is a backup Topsy Turvy. Who cares about your Radiant Elemental only having 2 health when it's swinging for 28 right now?

Lyra has the biggest grin on her face. You'll love getting this card out of Lyra because its just more spells, and you might even run it yourself because, FREE. I highly doubt you'll encounter a board where casting this is bad on any target. Good luck to you jokers, Lyra grants miracles.

Very true. The only problem is that Priest got a lot of bad spells to get out of Lyra in this expansion.

One more 0 cost spell for Miracle Priest.

Zerek the cloner like this card :)

This is why progress and innovation is bad for ... they took poor's Crazed Alchemist job and made a robot do it. 

I actually did need more backups for my Inner Fire (especially the ones that don't get destroyed by Skulking Geist)

Very versatile card. Buff your guys, make an opponents easier to kill, or swap an opponents high health minion then swap it again with twilight acolyte.

Is that a huge buff to combo Priest ?

backup Inner Fire for inner fire priest.
