Can you Death Grip a unit that has a weapon get might from both. Then attach that weapon to another unit during a showdown?
No, you cannot attach a weapon to another unit during a showdown.
Here is the breakdown of why this does not work, based on the rules and game mechanics:
1. Interaction with Deathgrip
When you play Deathgrip, you must choose a friendly unit to kill. If that unit has a piece of equipment (a weapon) attached, the equipment becomes unattached when the unit leaves play. According to Rule 452.1, unattached gear present at a battlefield is recalled to your base during the next Cleanup.
2. Equip Timing
Even though the equipment is detached when the unit dies, it is not available to be equipped to another unit during the showdown:
- Showdown Timing: During a showdown, the game is in a specific state. Even in an Open state, you cannot perform moves that aren't specifically allowed by the combat flow.
- Equip Timing: Attaching gear is a "limited action" that is generally performed during your Main Phase when the chain is empty and no showdown is occurring. There is no provision in the rules that allows you to attach gear to another unit during a showdown.
3. Buffs and Might Bonuses
- Buffs vs. Equipment: Buffs are removed when a unit leaves play. Equipment follows a different rule: gear detaches when its unit leaves the board. It is not destroyed, but it remains at the last board location until the next cleanup.
- Might Bonus: Rule 137.3.a states that a piece of gear's might bonus is only applied to the unit it is currently attached to. Once detached, that gear is no longer providing a bonus to any unit until it is successfully attached to a new one.
Summary
If you Deathgrip your own unit:
- The unit is killed and sent to the trash.
- The attached equipment detaches and remains at the battlefield.
- Because the showdown is currently ongoing, you cannot equip that detached gear to another unit.
- The equipment will be recalled to your base during the combat cleanup.
