I finally got Mercy today 
and was trying to figure out how to work her into teams. So I was wondering, what are people’s favourite teams with Mercy in them? Or how do you usually use her?
Eg I was looking at the classic Treant, Alchemist, Valkyrie, Banshee and wondering if I could replace Alchemist for Mercy once I get her leveled up a little bit? EDIT: Actually probably not, just realised that Treant mana blocks Mercy 
I sense a summoning spell at work here, summoning a @Lyya in 5… 4… 3… 2… 1…
My lineup was Mercy, Infernal King, Sheggra, Star Gazer; all fully traited.
Mercy comes into her full strength when fully traited. You’re going to need 12 Swamp Arcanes to do that.
Good news is that they are part of the Ultra Rare bundle this week, so you should be able to get some/all of them with lots of play and maps.
I like mercy with Gorgotha or Great Maw. Infernal king works well with her as well.
Hilarious… but sadly the capricious @lyya didn’t appear on cue…
Mercy is more effective then alchemists only in case you have her fully traited. Keep that in mind.
Sometimes only during the first round based on the teams. A mana generator tied to converting a single color is not that flexible. Plus the alchemist has that gold thing
Templar***, priest***, tyri***, mercy***. Deny all the things and watch the opponent’s strongest stuff just die of starvation.
I like:
Templar
Mercy
Moloch
Paladin
Green/yellow banner. Fully leveled and traited. And that’s four unique Whitehelm troops for kingdom bonus.
10Char
In before Lyya!
How many colors does it cover? I am too lazy to count.
Everything except purple, which Mercy transforms.
Sleep’n stuff!
Okay so yeah, Mercy teams?
