A combination of Mobile Toolkit and the Effigy.
Maybe something, that improves other units. Adding until the end of turn on one or more flips (attack, dmg, Df) or a +1 burning/poison to attack actions. It should have a good defense ability with a handicap, sth like "reduce any damage to 1, then the attacker may push this model up x", where x is the number of damage prevented." Also nice is "this model may not heal any Wd by itself or other models and is immune to any conditon given by other models."
As subtype it should be Spirit, Construct or Living, where Spirt AND Construct could be funny.
After a little brainstorming, here a suggestion:
Spirit of Engineering Peon, Spirit, Construct, Totem Costs 4
Df Wp Wd Wk Cg Ht
3 6 4 4 - 1
Abilities:
Insignificant
Df Scatterbrained: Reduce any Damage to 1, then the attacker may push this model up to x", where x is the number of damage prevented.
Unalterable: This model may not heal any Wd by itself or other models and is immune to any conditon given by other models.
Attack Action:
(1) Glimpsing Kiss By A Muse (MI 6/ Rst: Df/ Rg 1): Target suffers 1/1/1 damage. After succeding this model may be pushed up to the Wk printed on the Stat Card of the damaged model.
Tactical Action:
(1) Flash Of Genius (Ca 5/ TN: 12/ Rg 12): This action may only be taken once per activation. Place a Scrap Marker in base contact with target model.
Inflaming Idea: Until the end of turn, the target adds + 1 Burning to all of its attack actions.
Inspiring Dance: Until the end of turn, the target adds + 1 Poison to all of its attack actions.
Physical Power: Until the end of turn, the target gets to its damage flips.
Mental Power: Until the end of turn, the target gets to its attack flips.
