@Buhallin I think Relentless Assault still works, even if you do take your deliberately obtuse and RAW stance.
The card:
Let's say I play this card, paying for it with Strength, and target an Ultron Drone (1 HP)
> Deal 5 damage to a minion.
> If you paid for this card using a [physical] resource, this attack gains overkill.
So I deal 5 damage to the Ultron Drone. That sentence is fully resolved.
Then I move onto the second sentence. I paid for the card with a physical resource, so the attack (not the damage, but the attack itself - i.e the card itself) gains overkill.
Overkill - Rules Reference, Page 10, Keywords:
QuoteIf an attack with overkill defeats a minion, excess damage from the attack (damage beyond the minion’s remaining hit points) is dealt to the villain.
So we're still resolving the 2nd sentence, which now tells us the attack has gained Overkill. Which itself tells us that if the attack defeats a minion (which it did), the excess damage is dealt to the villain.
Nothing about the card's text being in 2 separate sentences prevents it from working as intended.
