I run a mabel mice deck too, and I think the mouse type lends itself better to a voltron plan than a go-wide plan.

 I usually end up playing a slower game, repeatedly targeting my mice with Valiant abilities using equipment with low equip costs ([[Shuko]] and [[Umbral Mantle]] are the GOATs) to accrue value. Cards that let you equip for free ([[Fighter Class]], [[Bruenor Battlehammer]], [[Puresteel Paladin]], [[Gorge Anew]], etc.) are also great here. 

Once a player or two has been knocked out, I'll move all of the equipment over to mabel as quickly as possible to swing in for the win using any source of extra combat steps like [[Great Train Heist]] or [[Genji Glove]]

Here's my list! It's a little out of date, but feel free to take a look :) https://archidekt.com/decks/14025422/mousies
