Ah point taken...but again bronze cards now play for 10 or 11 and even above without requiring a leader charge. Also I wouldn't include consume unit in that calculations since that's a separate interaction. Deathwish itself is a condition because without a charge or consume unit she bricks, then her ability has a condition and without a target it bricks. All in all I think the deathwish mechanic is what needs to be reworked not so much MirunaNot really, if Miruna seizes a 4 strength unit one gets a 4 str Miruna + taking 4 points from the opponent + getting a 4 str unit => 12 points for 9p + Consume (a Consume is also worth 1.5-2 points) => Miruna is a conditional 10.5/11 for 9p.
Honestly I would argue that Miruna gives value that would be ok'ish if unconditional and if conditional is not worth considering.
