Selfcraft Mechan is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
When this creature enters, you may sacrifice an artifact. When you do, put a +1/+1 counter on target creature and draw a card.
Complete guide
Selfcraft Mechan is a versatile blue artifact creature that offers utility by turning your redundant artifacts into permanent growth and card advantage. By dismantling your own machinery, you can bolster your board presence while keeping your hand full of options.
Understanding the Reflexive Trigger
Selfcraft Mechan features a special type of triggered ability known as a 'reflexive trigger.' When it enters the battlefield, you are first given the option to sacrifice an artifact. The second part of the ability—targeting a creature to receive a counter and drawing a card—only triggers if you actually choose to sacrifice something. This means you do not choose a target creature until after you have made the decision to sacrifice an artifact.
Step-by-Step Resolution
First, the Mechan enters the battlefield and its initial ability goes on the stack. When this resolves, you decide whether to sacrifice an artifact. If you do, the reflexive ability ('When you do...') triggers and is put onto the stack. At this point, you choose the target creature. Players can respond to this second ability. Finally, if the ability resolves, the target creature receives a +1/+1 counter and you draw a card.
Common Mistakes to Avoid
A critical detail to remember is that if the target creature becomes illegal before the reflexive ability resolves (for example, if it is destroyed in response), the entire ability fails. In this scenario, you will not put a counter on anything and, crucially, you will not draw a card. Also, remember that since the sacrifice happens during resolution of the first trigger, you cannot wait to see if the draw is successful before deciding to sacrifice.
When to Play Selfcraft Mechan
This card is best used when you have artifacts with 'dies' triggers or 'enters' triggers that have already provided their value. It acts as a sacrifice outlet that converts low-impact board pieces into high-impact resources. It is particularly effective in decks that can protect their creatures, ensuring that the reflexive ability resolves successfully.
Interaction examples
When Selfcraft Mechan enters, you choose to sacrifice Solemn Simulacrum. This triggers two abilities: the Mechan's reflexive ability to buff a creature and draw a card, and the Simulacrum's own ability to draw a card when it dies. You end up with a +1/+1 counter on a creature and two fresh cards in hand.
If Roaming Throne is on the battlefield with 'Robot' or 'Artificer' chosen, Selfcraft Mechan's entry ability triggers twice. You can sacrifice two different artifacts to trigger the reflexive ability twice, allowing you to put two counters on creatures and draw two cards total.

How it works : Selfcraft Mechan
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
You don’t choose a target for Selfcraft Mechan’s ability at the time it triggers. Rather, a second “reflexive” ability triggers when you sacrifice an artifact this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal. Then if the target creature is an illegal target as the reflexive trigger tries to resolve, it won’t resolve and you won’t draw a card.
