If you want it to be attractive as a target for cc, it needs to have at least 4 atk and at most 5 hp.
Best available comparison is phoenix, which also gives a massive discount on the revive (but can be removed entirely) and has atk equal to cost so this cannot really afford to be much more expensive than its atk value if its supposed to actually trigger much (due to being squishy).
Also, what would its purpose be? Since you want to discourage self triggering you probably want to make it costly enough to not be suitable as a deck thinner for combodecks, food for cremation/orochi (black cat and minor phoenix will likely not be outdone in cost efficiency for repeatable use), but in that case it would mostly counter cc in the end up to a limit. maybe brawl synergy might be interesting. (Future) Cards that cause creature combat or sac creatures and have amplified effects based on stats of the sacrifice (like catapult) can be interesting for this i suppose.
