Hi @xzxixin,
Thank you for your bug report. However, we are not certain if it qualifies as a bug.
Card “01029a” (Iron Man) states:
You get +1 hand size for each [[Tech]] upgrade you control.
According to the rules:
“you control” refers to cards in play currently under that player’s control.
This raises an important question:
Is an upgrade card attached to an enemy still controlled by the owner of that card?
The “OWNERSHIP AND CONTROL” and “UPGRADE” sections in the rulebook do not provide a clear answer, which leaves us uncertain about whether this is indeed a bug.
If you have any further insights or questions, please feel free to continue this discussion.
