I agree that attack values LOWER than 3 / 4 normal/upped are uncommon but something like this with Chrys and SoP could prove VERY strong... very very strong, perhaps too strong.
The idea I have in mind would be a deck like:
Hover over cards for details, click for permalink
4t9 4t9 52g 52g 52o 52o 52o 52r 52r 52r 542 542 542 542 542 542 542 542 542 5i5 5i5 5i5 5i5 5i5 5i5 5ib 5ib 5ib 5j2 5j2 8pp
Where Relic is Armorson.
If you need to bump Armorson one time to get the ball rolling on consuming souls then you toss one of the deck's own tiny creatures out to sacrifice. Once you gobble a couple souls the Armoson is able to consume almost any creature damage played by opponent because the stat tied to consuming (ATK) is the stat boosted by use of ability (Consume is +1|0). This is somewhat like Otyugh except harder to handle as the game has much fewer PC (handle Armorson) options than CC (handle Oty).
It could also be that the card is fine as it is and I'm hallucinating OP scenarios that are not feasible.
