If that's the case, then this didn't do a great job of fulfilling that flavor, since it bounces itself and you could just put it back on the same creature. I'd just kill the clause about returning to your hand when it runs out of counters, and it would be more like a versatile Rancor, which would be powerful but balanced.
Do you think the card would work if it was 5 cost instead, maybe the same 5 cost as Gudako, the commander?
In the source, each master has a command seal that can only be used 3 times. Gudako is a tad different because she has tons of servants, not just one. The command seal can be used to allow the servant to overcome their natural limits.
