Enthusiastic Mechanaut + Mystic Forge + Sensei's Divining Top
Overview
With Mystic Forge on the battlefield you may cast artifact spells from the top of your library; Sensei's Divining Top can be used to rearrange or replace that top card before you cast; when you cast an artifact spell from the top, follow the normal casting steps , and Enthusiastic Mechanaut’s static cost-reduction ("Artifact spells you cast cost 
less to cast.") reduces the total cost when that spell is cast (costs are determined and locked in as part of casting ). Sensei’s Top’s two abilities can be ordered so you draw then reorder or reorder then draw as desired (see Ruling [2016-06-08]). Mystic Forge does not let you play lands (including artifact lands) from the top of your library because lands aren’t cast as spells (Ruling [2019-07-12]).

If you want a particular artifact on top, use Sensei's Divining Top's ability to look at the top three and reorder or, alternatively, activate Top's and then activate Top's 
in response as described in Ruling [2016-06-08] so you draw then reorder the new top [Ruling [2016-06-08]].

With Mystic Forge on the battlefield, check the top card. If it is an artifact card (or a colorless spell), Mystic Forge gives you permission to cast it from the top of your library (this is part of the card's oracle text; casting still follows the normal casting rules) .
Step 3
Announce that you are casting the artifact from the top of your library. The card moves from the library to the stack as the spell is being cast .
Step 4
Determine the spell's total cost and apply cost reductions and increases. Enthusiastic Mechanaut's static ability reduces the total cost of artifact spells you cast by and is applied when the total cost is determined/locked in .
and is applied when the total cost is determined/locked in .Step 5
Pay the locked-in costs (you may activate mana abilities before paying if needed) and finish casting the spell per the normal casting steps in .
Step 6
If the spell resolves, it becomes a permanent on the battlefield (artifact or artifact creature) under your control , .
Resolution
You may use Sensei’s Divining Top to place an artifact card on top of your library (by using its and/or abilities in whichever order you choose, noting the interaction in Ruling [2016-06-08]). While Mystic Forge is on the battlefield you may then cast that artifact card from the top of your library; when you announce casting you move the card to the stack , determine the spell’s total cost and apply cost reductions (including Enthusiastic Mechanaut’s reduction) to lock in the cost , pay costs, and when the spell resolves it becomes a permanent (artifact or creature) on the battlefield , . You cannot cast an artifact land from the top because lands are not cast as spells (Ruling [2019-07-12]).
