I suggest making the Ancestry cards care about sharing creature types. So if you have a Monk in your yard you can still return it tapped and attacking.

Ancestry 2W - When a creature you control with Ancestry attacks, you may pay . If you do, return this creature from the graveyard to the battlefield tapped and attacking if it shares a creature type with the attacking creature. Sacrifice it at the end of turn.

Hold on, your wording doesn't make sense. What you're suggesting is that when a Monk is in the yard WITHOUT Ancestry, you can still return it. But then whats the cost of Ancestry if it doesn't have Ancestry on the card?

Your wording would turn creatures with Ancestry into like... Ancestry beacons, which can get any creature back if it shared a type. Not that it exists in this set but a changeling with Ancestry could theoretically revive any creature for a turn?

As your actual wording stands, it's exactly the same except that it's more restrictive as any Ancestry card that doesn't share a type with others will become useless.

If you're wondering about why I included the Remnant subtext it's because then it's an easy way to have other cards reference reanimated things.
