Changing it to Dark type can have some synergy with other Dark support cards. Genex Ally Powercell will make it's attack be at 2300, Caligo Claw Crow for some swarming potential, Dark Voltanis if you use counter trap cards, or Dark General Freed to negate targeted spell effects.
On their own, their attacks may be considered low, but they have versatile effects depending on the attributes of other monsters on the field. This also includes your opponent monster's attributes, so each of them can have both effects active. Having 2000 attack and negate monster's effects, or be able to attack multiple times, your Homonculus can help control which ones you need.
A great beater card which allows you to change its attribute to maximise the use of filed spells on the field.
Combine this card with Bastion's skills that place a powerful field spell when you take LP damage to create a decent beatdown deck. This card can also change its attribute to avoid having its attribute changed by various Weevil decks.
