45 nora Deploy a Prisoner Elf with 0/0/0/0/1 for stats under your opponent's control and ownership on target space. It has Unstable (will leave play at end of turn). Plenty of things key off killing opposing units, so here's a way to create an opposing unit just to kill it. I figured it fit best in UD.
an IS version for political martyr would be funny, but the cost maybe to 30? and give it like 7hp to survive traps but still one shotted by everything in UD. Depending on combos that aren't coming to mind, maybe nora cost 30 on the unit as well.
but you're paying 30/45 nora for a swarm unit in that case which the swarm unit is already back loaded as is. I see the advantage other than making a swarm unit get plus 1 which could be met by just running banner or unholy statue lol
