So I was thinking about a Majordomo Staghelm concept for a legendary.
The idea would be that he keeps turning into flame cat or scorpion based on turns or number of minions present on board.
if he keeps changing turn by turn, maybe he could go into the cat form as a battlecry and it would need charge so you can actually attack with it before scorpion form. Then at the end of your turn (or the start) he could change to scorpion and so on.
If the shapeshift is minion based, flame cat could be 2 or less, scorpion could be 3 or more. Something like that it's not that relevant how you divide it. The card would need a battlecry that decides the form based on the rule, and It would be cool it triggered somehow again and again at the start of your turn so the form would change based on board.
I was thinking the card could cost 8 for 4 attack and 12 health (at least). he needs high health I think so he has a chance to shapeshift before killed. Of course the current form would inherit the remaining health of the previous form (or not so you would have to kill it in one turn, that could be interesting too).
So ideas for the cat form: I thought it would be fun if you hit the cat but not kill it, it would summon a copy with the remaining health (and it would be textless so just a body). Another one is that maybe it could do double damage back to the opponent if attacked.
Scorpion: the only thing it did in wow is cleave so I thought either it could hit an opponent and deal 2 damage to the adjacent minions (2 for each, so 8 dmg total) or hit the opponent and deal 1 dmg to everyone else (swipe style).
Both forms currently would be 4 attack 12 health for 8 or 9 mana. If their abilities used well it could ramp up around 8 dmg.
So what do you think? My problem is that it's way too complicated to put in card texts efficiently. I tried and it was a mess
